THE ULTIMATE MATERNITY & NURSING BRA GUIDE:

How to Choose, How Many You Need, and Many More Questions Answered

Let’s be real - shopping for bras is rarely fun.

What size am I? How do I choose the right ones? How many do I need? They cost HOW much?

And bra shopping on top of being pregnant or nursing? Yea, we feel for you. Which is why we’ve made this easy.  

You have questions, we have answers.

INTRODUCTION TO NURSING & MATERNITY BRAS 

From what they are, to where to buy them – let’s cover the basics of nursing bras and maternity bras. 

Why do I need a maternity or nursing bra?

Because pregnant and lactating boobs are special. Seriously. Pregnancy and postpartum hormones do crazy things, and your boobs are along for the wild ride. And we’re not just talking about first trimester breast tenderness and your rapidly growing cup size. Your boobs are busy evolving into milk machines.  

During pregnancy and while nursing, your breast tissue can be up to 35% heavier! Combine that with the uncomfortable statistic that 80% of women are wearing the wrong bra size to begin with...it’s definitely time to get a maternity bra or nursing bra that fits and supports. A supportive nursing bra is your best tool to maintain breast health, provide relief and comfort and promote tissue recovery after pregnancy and nursing. Wearing a proper fitting bra can also help with posture, eliminate stress on the back, and make clothing fit better. 

What is the difference between a maternity & nursing bra? 

To us at Motherhood Maternity, we’re all about keeping it easy with the real solutions you need during pregnancy and after. That’s why all of our bras can be worn while pregnant and while nursing. There is no difference between a maternity bra or a nursing bra to us, as we’ve created supportive and comfortable bras that are made for pregnancy and after, with solutions for when – or if – you nurse. Find your favorite bra during pregnancy – and keep on wearing it well after baby arrives. Some moms love our bras so much that they’re still wearing them WAY after they’re done breastfeeding.  

In short, maternity bras = nursing bras

What is a maternity or pregnancy bra? And why do I need one 

A maternity bra is made with your pregnancy needs in mind. When you’re pregnant, your breast tissue can be up to 35% heavier! Your breasts can also be tender and extra sensitive. So, wearing a maternity bra made for pregnancy will provide you with superior comfort and the essential support that you need. Motherhood Maternity’s collection of maternity bras, including Sleep Bras, are designed to keep you supported – and our wireless and seamless styles are designed to keep you comfortable 24/7.  

Your breasts are also rapidly changing sizes during pregnancy and after birth. So, you’re going to want to buy something that will last through all of the stages of motherhood. All of our pregnancy bras are nursing friendly, so if you decide to nurse, you can wear those same maternity bras you bought and wore in the 2nd trimester after baby arrives while feeding (though we do recommend re-measuring yourself after birth to ensure optimal support and comfort!).

When to buy a maternity bra

Every woman is different and will experience different changes to her body during pregnancy, so there is no right answer to when to buy a maternity bra. BUT, Motherhood Maternity has been around long enough to give you some pointers. We have tracked a lot of women’s changing sizes during and after pregnancy, and these are the changes to your bust line that you can expect during each trimester of pregnancy, by the averages. Generally, we recommend you start buying maternity bras in your first trimester. Keep reading for more details on types and timing. 


FIRST TRIMESTER 

Most women will experience breast growth during the 1st trimester, so it’s a great idea to get yourself properly measured now. If you are wearing the wrong size, you are not getting the support you need, and this will likely add to any pregnancy breast discomfort you’re experiencing. Your pre-pregnancy bras may still fit fine during this early stage (if you wear the right size!), so we recommend starting with a Sleep Maternity Bra to keep yourself supported and comfortable throughout the night.  

SECOND TRIMESTER 

You’ll usually notice the largest increase in your breast size during the second trimester, going up an average of 1 band and 2 cup sizes, as your ribcage also expands with your growing baby bump. Your bra should fit comfortably on one of the tighter hooks so that you can loosen the bra into 3rd trimester as your ribcage continues to expand. We recommend making our best-selling Seamless Maternity Bra your everyday go-to, as its flexible fit will accommodate size fluctuations into your third trimester. 

THIRD TRIMESTER 

It’s possible your cup or band size will increase in the third trimester, so it’s important to remeasure if things are getting tight or uncomfortable. If you are buying a new bra, we recommend ensuring it fits well on the loosest hook so you can tighten the bra after birth. For maximum comfort and fit flexibility, we recommend our wireless, hardware-free Seamless Rib Knit Maternity & Nursing Bra. The size you are at the end of your third trimester is usually what will fit right after baby arrives, and all Motherhood Maternity bras are nursing friendly, so you can keep on wearing your maternity bras after baby arrives.  

What is a nursing bra? And why do I need one? 

A nursing bra is designed for all of your postpartum needs. Whether you are nursing or not, Motherhood Maternity’s collection of nursing bras is designed specifically to support pregnant and postpartum breasts as they rapidly change sizes throughout your journey. Our seamless and soft bras are wire-free for maximum comfort, and offer gentle, stretchy support that grows with you. And because the last thing you want to do with a newborn is go bra shopping – these bras are designed to fit before and after baby arrives. 

And of course, a nursing bra wouldn’t be a nursing bra without effortless, one-handed breastfeeding access. All of Motherhood Maternity’s bras are breastfeeding-friendly with effortless clip-down or pullover functions to get baby – or pump – latched as quickly as possible. For the fourth trimester right after baby is born, a wire-free bra, like our Seamless Nursing Bra, is a great everyday bra as it will be less restrictive on your breast tissue, which will help you to avoid discomfort, pinching and clogged milk ducts.    

When to buy a nursing bra 

The best times to buy a nursing bra are before baby arrives so you have everything you need directly after birth, and then again 10-12 weeks postpartum when your bra size will likely change. 

BEFORE BABY’S ARRIVAL 

We recommend buying nursing bras at the end of your second trimester or in your third trimester before baby arrives. A bra that fits on the loosest hook in your 3rd trimester should fit and support you well right after baby’s arrival and give you the option to tighten the bra as your ribcage begins to contract. Our Seamless Bra was made with pregnancy and postpartum size fluctuations in mind and will be your best friend while dealing with highs and lows of stabilizing your milk production.  

10-12 WEEKS POSTPARTUM & BEYOND 

After you’ve given birth, the best time to buy a nursing bra depends on when your milk production stabilizes and what your specific wardrobe needs are. Right after birth, your boobs can fluctuate rapidly as you are adapting to baby’s demands! Plus, you are still healing and recovering from pregnancy right after birth, with organs – and your ribcage! - shifting back into pre-pregnancy mode. Because of this, we recommend waiting 10-12 weeks postpartum to remeasure yourself and get new nursing bras for the next phase of your breastfeeding journey. And if you’re going back to work, it might be time for a nursing-friendly underwire bra or a hands free nursing & pumping bra that makes those pumping sessions a little easier.  

SELECTING A MATERNITY & NURSING BRA STYLE 

The maternity bra and nursing bra styles Motherhood Maternity offers, and how to find the perfect one for you. 

HOW TO CHOOSE A MATERNITY BRA 

Motherhood Maternity offers a variety of maternity bra styles to meet your needs. When choosing a maternity bra, select one not only fits your style needs, but also your physical concerns. 

  • If you’re concerned with shaping, lift & versatility, try our Underwire Maternity Bra or our Molded Wireless Maternity Bra. These options have the look and fit of your favorite bra, with the added versatility of being nursing-friendly for later. 
  • Are tender, sore boobs your main concern? Get yourself a soft and support Maternity Sleep Bra for ‘round the clock support. 
  • If you are most concerned with size fluctuations, get a bra that is designed to grow with you. Our top-rated Seamless Maternity Bra is constructed to provide a flexible fit that covers a range of sizes, instead of just one cup and band size. This means it will continue to support and fit even as you grow.  
  • Is your back feeling the strain? If back aches and pains are your main concern, you need a well-fitted bra that offers medium or firm support. We recommend the Rib Knit Seamless Maternity Bra and our Full Coverage Underwire Maternity Bra.  


HOW MANY MATERNITY BRAS DO I NEED? 

At a minimum, it’s recommended to have four (4) maternity bras on hand: 

  1. One to wear for all-day comfort 
  2. One to wash because boob sweat happens! 
  3. One to sleep - 24/7 support is 100% necessary 
  4. One to keep so you’re ready for anything 

It’s good to have different styles as well so you have options on what looks best under your outfit. Your Maternity Bra Drawer should have at least one of each type of bra – double up on your favorite! 


HOW TO CHOOSE A NURSING BRA 

If you’re not sure how to choose a nursing bra, we can help. Motherhood Maternity offers a variety of nursing bra styles to suit any of your needs – from the early days of nursing to when you’ve basically gone pro. Select a bra that meets your concerns and style needs. 

  • If you’re concerned with versatility and coverage, try our Underwire Nursing Bra or our Molded Wireless Nursing Bra. These options fit like your favorite non-nursing bra but have the clip-down straps you need when duty calls. This is the bra you’ll wear to the office, for date night, and when you need a little extra support or lift under clothes.  
  • Are you looking for that marathon-feeding and nap-friendly bra? Get yourself a soft and support Nursing Sleep Bra. This comfortable wrap style bra is free of hardware so it is the choice for soft, light support that will keep your nursing pads in place. 
  • If you are most concerned with size fluctuations, get the nursing bra that was expertly designed to support and fit your boobs whether your engorged or running on empty. Our award-winning Seamless Nursing Bra is constructed to provide a flexible fit that covers a range of sizes, instead of just one cup and band size.  
  • Are clogged ducts or mastitis on your mind? The Rib Knit Seamless Nursing Bra is a pull-over style that offers 360-degrees of support, without any wires. You’ll get the support and lift you want, without any pinching or irritation.   
  • Are you breastfeeding and pumping? Get a bra that allows you to do both. If you have a traditional breast pump with flanges, like the Medela, Spectra or Evenflo, the Hands Free Nursing & Pumping Bra will allow you to keep the pump in place without holding it. If you have a wearable pump, like the Elvie or Willow, the 2-in-1 Nursing & Pumping Bra was made to hold these pumps with the prefect amount of compression.  


HOW TO CHOOSE A PUMPING BRA 

When choosing a pumping bra, the most important thing to consider is what type of pump you have. Motherhood offers bras for both traditional pumps and wearable pumps. 

  • If you have a traditional breast pump with flanges, like the Medela, Spectra, Ameda, or Evenflo, the Hands Free Nursing & Pumping Bra will allow you to keep the pump in place without holding it. Simply unclip the bra strap and insert the flange into the openings to pump hands-free. You can pump on one or both sides and pull the inner bra panel aside to breastfeed. 
  • If you have a wearable pump, like the Elvie, Willow or Freemie, the 2-in-1 Nursing & Pumping Bra was made to hold these pumps in place. This bra offers the optimum about of compression for an efficient and effective pumping session, every time. Clip the bra straps down to use this bra for breastfeeding as well.  


HOW MANY NURSING BRAS DO I NEED? 

At a minimum, it’s recommended to have four (4) nursing bras on hand: 

  1. One to wear for all-day comfort & nursing access 
  2. One to wash because leaks happen! 
  3. One to sleep - 24/7 support is 100% necessary 
  4. One to keep so you’re ready for anything - baby spit up can mean multiple changes a day! 

It’s good to have different styles as well so you have options on what looks best under your outfit. Your Nursing Bra Drawer should have at least one of each type of bra – double up on your favorite!

At 7 months, I bought an XL and these bras are so comfortable. They have a bit of room to grow once my milk comes in, and I’m confident that these will do the trick. I wanted something a little more full-coverage and these are just perfect! Typically, I take the padding out of bras, but I kept them in this time because they are so comfortable, I don’t even mind the padding. I bought 2 black and 2 nude bras, and I couldn’t say enough good things about them.” – Real Mom, Haley

WRAP MATERNITY AND NURSING SLEEP COTTON BRA

Wearing a bra while sleeping during pregnancy and when nursing is essential to help to prevent sagging as your breast tissue changes and your size fluctuates. It also keeps nursing pads in place during those early days after baby arrives. This is more than just a sleep bra – it’s a “I don’t want to wear a bra” bra.  

“I love this bra! It is so comfortable while still providing support. I tried another comparable bra from a well-known (and pricier) brand that did not fit well at ALL, so I’m sticking to this one! At 30 weeks pregnant, I am currently wearing 36DD and this bra in Medium has been a life saver. My breasts feel lightly and comfortably supported, without the band being tight. I could in fact still grow a bit into the band seeing as it can still stretch out more (I think the S might fit me band-wise but not cup-wise). I want more of these for nursing, I’m just waiting until the final weeks of pregnancy to see if I stick to Medium or get them in Large. Completely recommend, for sleeping or lounging around the house!” – Real Mom, Marian

“Best Fit Ever. I've tried countless maternity bras since getting pregnant without much luck, the fit was always off in some way. The second I tried this one it was perfect! No spilling, gapping, or pinching anywhere plus tons of hook options to make bigger or smaller. I don't often write reviews but had to for this bra, definitely recommend!” – Real Mom, Brittney

THE BEST BRAS FOR EVERY STAGE OF PREGNANCY & POSTPARTUM 

Your boobs deserve a lot of support during pregnancy and while nursing. They’re working overtime for baby and go through a lot of changes throughout the journey. And a proper fitting bra will relieve breast discomfort, provide support to prevent sagging, and help to alleviate pressure from your back. Not sure where to start? These are the bra styles you need for each trimester and step of the journey.  

FIRST TRIMESTER 

WHAT’S HAPPENING TO YOUR BREASTS: During the first trimester, you are definitely starting to get fuller, but your size may not have increased quite yet. You are likely also experience tenderness – usually one of the first signs of pregnancy! Now is a great idea to measure yourself, since most women are wearing the wrong size, and you could be making any discomfort worse if you’re not getting the proper support. 

THE BEST BRAS FOR THE 1ST TRIMESTER:  

  • SLEEP BRAS: For sore, tender breasts, the Wrap Sleep Bra is an absolute must-have. You will definitely want this maternity sleep bra to keep yourself supported and comfortable all night long. It’s also the perfect style for lounging around at home. We recommend getting at least two Sleep Bras, so you always have one to wear. 
  • SEAMLESS BRAS: If breast tenderness is making your underwire bras look like torture devices, we recommend starting your collection of Seamless Maternity Bras now. This grow-with you style has no underwire and is soft and stretchy. For a pull-over option, try the Rib Knit Seamless.  

SECOND TRIMESTER 

WHAT’S HAPPENING TO YOUR BREASTS:During your second trimester, you will usually notice the largest increase in your bust size! On average, you can expect an increase of two cup sizes and one band size as your ribcage begins to expand to make room for your growing bump. If you haven’t needed a new bra yet, you definitely will now! 

THE BEST BRAS FOR THE 2nd TRIMESTER:  

  • SLEEP BRAS:Though your boobs may not be as tender as they were in those earlier days of pregnancy, having some extra support while you sleep is key. The Wrap Sleep Bra will keep your breast tissue – and back – supported, and it’s completely hardware-free design will keep you comfortable. 
  • SEAMLESS BRAS: These grow-with-you Seamless Maternity Bras offer the perfect amount of support, lift, and comfort all pregnancy long. The flexible fit of this maternity bra means it will comfortably fit you even as your ribcage and bust continue to expand.  
  • STRUCTURED BRAS: Maternity leave hasn’t started yet – so you’re probably going to want some structured bras to wear to work. Our Full Coverage Underwire Maternity Bra smooths and contours and will continue to support you into the 3rd trimester and beyond with its four rows of back hooks.  
  • Fit Tip! Your bra should fit comfortably on one of the tightest hooks, so that you can loosen the bra into your third trimester as your ribcage begins to expand. 

THIRD TRIMESTER 

WHAT’S HAPPENING TO YOUR BREASTS:During your third trimester, the bras you bought during your 2nd trimester should still fit, but you will probably need to move to a looser hook as your bust and ribcage continue to expand as baby is getting bigger and bigger! Comfort is the name of the game by the end of pregnancy since little feet may be digging into your ribcage making bras – and just breathing or eating – uncomfortable.  

THE BEST BRAS FOR THE 3RD TRIMESTER: 

  • SLEEP BRAS: With the discomfort you may be feeling simply from being really, really pregnant, the Maternity Sleep Bra will be your go-to maternity bra for lounging at home, napping on the couch, or dozing off. Soft and free of all hardware, it offers light support without adding any additional pressure of an underwire. 
  • SEAMLESS BRAS: Even as your bust and ribcage continue to expand during the 3rd trimester, your Seamless Maternity Bras should still be feeling comfortable and supportive as they are meant to fit across multiple sizes. The Rib Knit Seamless Maternity Bra is a great choice for optimum comfort, as it offers 360-degree support in a comfortable pull-over design. 

HOSPITAL BAG & FIRST WEEKS WITH BABY 

WHAT’S HAPPENING TO YOUR BREASTS:Those first hours, days and weeks after baby is born, there is A LOT going on with your body. It is working in overtime keeping up with baby’s demands, and your boobs can take on different shapes and sizes by the hour as your milk comes in, your baby cluster feeds, and you figure out this whole breastfeeding thing. Comfortable nursing bras and tops are absolutely essential.  

THE BEST BRAS FOR HOSPITAL BAG & FIRST WEEKS WITH BABY: 

  • SLEEP BRAS: When you finally get a moment to sleep – your boobs are still hard at work. And leaks are bound to happen. Wearing a Nursing Sleep Bra will keep nursing pads in place and provide light support all night long. Simply pullover to nurse whenever baby is hungry.  
  • SEAMLESS BRAS: You know who loves a newborn? All your family and friends – who are going to want to come and meet your newest arrival. When you absolutely must put a bra on, make it a Seamless Nursing Bra. Its fit flexibility will keep you supported and comfortable through all your size fluctuations. And its straps clip-down for easy nursing. 
  • NURSING CAMI: Okay, so this isn’t technically a bra. But it’s a nursing must-have. This simple but essential nursing cami with built in shelf bra and clip down straps provides added support when worn with a bra, or light support when worn alone. Layer it under everything to make any outfit nursing friendly. 
  • PUMPING BRA: You never know when you are going to need to start pumping. If your baby has hard time latching, you might need to pull the pump out right away. And having the right bra makes pumping so much easier. If you have a traditional breast pump with flanges, the Hands Free Nursing & Pumping Bra is a lifesaver – just put them in the provided slots and do your thing. You can even pump on one side, while nursing on the other. If you have a wearable pump, like the Elvie or Willow, try the 2-in-1 Nursing & Pumping Bra, made specifically to hold these pumps in place with the perfect amount of pressure to maximize each pumping session. 

 

FOURTH TRIMESTER & POSTPARTUM NURSING 

WHAT’S HAPPENING TO YOUR BREASTS: After your first few weeks with baby, your milk supply will begin to stabilize, and you can expect less drastic changes in size fluctuations. Around 12 weeks postpartum is when we recommend you remeasure yourself for new bras.  

THE BEST BRAS FOR FOURTH TRIMESTER & POSTPARTUM NURSING: 

  • SLEEP BRAS: Nighttime feeds are still on the schedule, and leaks are still bound to happen, so wearing a Nursing Sleep Bra and having nursing pads on hand is still a must. 
  • SEAMLESS BRAS:For those long days on the couch nursing baby, a Seamless Nursing Bra, like this Rib Knit Seamless Nursing Bra is still a must. This supportive and sporty bra is also great for stroller walks and light activity as you try to fit in some time for yourself.  
  • STRUCTURED BRAS:Whether you’re headed back to work or just for a night out, a great Underwire Nursing Bra or molded Wireless Nursing Bra gives you the look, feel and fit of a traditional bra – just with the added function of nursing clips.  
  • PUMPING BRA:Whether you’re an exclusive pumper, or only do it once in a blue moon, a pumping bra is 100% necessary. If you have a traditional breast pump with flanges, the Hands Free Nursing & Pumping Bra is a lifesaver – just put them in the provided slots and do your thing. You can even pump on one side, while nursing on the other. If you have a wearable pump, like the Elvie or Willow, try the 2-in-1 Nursing & Pumping Bra, made specifically to hold these pumps in place with the perfect amount of pressure to maximize each pumping session. 


FINDING YOUR MATERNITY & NURSING BRA SIZE 

How to take your measurements and ensure a perfect fit for your maternity and nursing bra. 

HOW TO MEASURE FOR A MATERNITY BRA & NURSING BRA 

They say 80% of women are wearing the wrong bra size…don’t be one of them! Measuring yourself to find the perfect bra fit is essential. To measure yourself, you’ll need a measuring tape. 

Prefer to watch a video on how to measure? Check out our Bra Fit Guide

A few tips for success before you get started: 

  • Measure yourself in a well-fitting, non-padded underwire bra if possible. This will give you the most accurate results. Wearing a padded or push up bra could give you a false cup size.  
  • It’s best to measure yourself in just your bra or in a thin tee shirt or camisole. 
  • Note where the ruler starts on your measuring tape, this is where your measurement starting point. Some measuring tapes start right at the edge, while others have a border before the ruler.  
  • Having a partner or friend do the measuring for you may make things easier! If you’re measuring solo, do it in front of a mirror.  
  • If you are currently nursing, try to measure yourself when your breasts aren’t overly full, or completely empty. We recommend about an hour after your last feeding or pumping session.  

 

If You’re Measuring Yourself 

FIRST, FIND YOUR BAND SIZE 

A perfect fitting band should lay flat across your back, parallel to the floor. Grab a measuring tape and make sure you’re wearing a well-fitting, non-padded bra. 

  1. STEP ONE: Wrap the measuring tape snugly around your rib cage, just under your bust. If you are wearing an underwire bra, tuck the tape under the wire. 
  2. STEP TWO: Make sure the tape measure is flat against you and parallel to the floor all the way around, check yourself out in a mirror to confirm. 
  3. STEP THREE: Exhale and take your RIB CAGE MEASUREMENT, ensuring your fingers are not under the measuring tape.  
  4. STEP FOUR: Use the chart below to determine your band size. 

Example: Let’s say your RIB CAGE MEASUREMENT is 31”. This makes you a 34 BAND SIZE  

    RIB CAGE MEASUREMENT
  • 27-29"
  • 30-32"
  • 33-34"
  • 35-38"
  • 39-41"
  • 42"
  • 43-45"
  • 46-47"

  • 34
  • 36
  • 38
  • 40
  • 42
  • 44
  • 46

THEN, FIND YOUR CUP SIZE 

Your breasts should fill your bra cup without spilling over or gapping – and when wearing an underwire, it shouldn’t poke you.  

  1. STEP ONE: Wrap the measuring tape loosely around the widest part of your bust. 
  2. STEP TWO: Make sure the tape measure is flat against you and parallel to the floor all the way around, check yourself out in a mirror to confirm. 
  3. STEP THREE: Inhale and take your measurement, ensuring your fingers are not under the measuring tape. 
  4. STEP FOUR: Subtract your BAND SIZE from your BUST MEASUREMENT. This will give you your cup size, every inch difference equals one cup size. Use the chart below to confirm. 

Example: Let’s say your BUST MEASUREMENT was 38” and your BAND SIZE is 34. 38 – 34 = 4”. You are a 34D. 

BUST MEASUREMENT minus your BAND SIZE = your CUP SIZE

If Someone Else is Measuring You 

FIRST, FIND HER BAND SIZE 

Grab a measuring tape and make sure she’s wearing a well-fitting, non-padded bra. It’s best to measure her in her bra only, or with just a thin tee-shirt or cami over her bra. You’re going to want to take a tight measurement. 

  1. STEP ONE: Wrap the measuring tape snugly around her, just below her bust. It may be easiest to stand facing her back so you can get the tape as flat to her ribcage as possible (which may be difficult to do from the front if she is pregnant).  
  2. STEP TWO: Position the tape measure under her underwire (if she’s wearing one) and make sure the tape is flat against her ribcage and is parallel to the floor all the way around. 
  3. STEP THREE: Ask her to exhale and snugly bring the two ends together to get her RIB CAGE MEASUREMENT.  
  4. STEP FOUR: Use the chart below to determine your band size. 

Example: Let’s say her RIB CAGE MEASUREMENT is 36”. This makes her a 38 BAND SIZE  

    RIB CAGE MEASUREMENT
  • 27-29"
  • 30-32"
  • 33-34"
  • 35-38"
  • 39-41"
  • 42"
  • 43-45"
  • 46-47"
    YOUR BAND SIZE
  • 32
  • 34
  • 36
  • 38
  • 40
  • 42
  • 44
  • 46

THEN, FIND HER CUP SIZE 

Unlike her rib cage, which should be measured tightly, her bust should be measured loosely. 

  1. STEP ONE: Ask her to extend her arms out at her sides. Slide the tape measure around the widest part of her bust. 
  2. STEP TWO: Making sure the tape is parallel to the floor and even around her back, ask her to take a deep breath in, then loosely measure her bust. 
  3. STEP THREE: Subtract her BAND SIZE from her BUST MEASUREMENT. This will give you her cup size, every inch difference equals one cup size. Use the chart below to confirm. 

Example: Let’s say your BUST MEASUREMENT was 41” and your BAND SIZE is 38. 41 – 38 = 3”. She is a 38C. 

BUST MEASUREMENT minus your BAND SIZE = your CUP SIZE

WHEN TO MEASURE FOR A MATERNITY BRA

We wish there was that magic timeframe that all pregnant women should measure themselves for a perfect fitting maternity bra. But in reality, every pregnancy is unique and your bra size may change several times (which is why moms are obsessed with our fit-flexible Seamless Bra).  

For most moms-to-be, your bust line is one of the first things to grow, and your breast tissue and ribcage will continue to change throughout pregnancy and postpartum, especially while nursing. For the best support and fit, you will need to remeasure yourself throughout your pregnancy at least 3 times: 

  1. During the 1st Trimester:When you first need a Sleep Bra 
  2. During the 2nd Trimester*:When you notice the most growth 
  3. Around 12 Weeks Postpartum,or once your milk production is established if breastfeeding: When your rib cage and breast size may decrease 

 

  • *Most women experience the most breast growth during the 2nd trimester, but it’s possible you will experience significant changes into the 3rd trimester. If your bra is getting uncomfortable or is no longer as supportive as it used to be, go ahead and remeasure yourself.  

WHEN TO MEASURE FOR A NURSING BRA

Motherhood Maternity bras are made for maternity to nursing, so we recommend that you begin to measure yourself and start wearing our bras during pregnancy. Since your breasts and rib cage size will fluctuate during pregnancy and after birth, it’s a great idea to measure along the way and get yourself setup with an assortment of nursing-friendly bras long before baby is here. The size you are wearing during your 3rd trimester should fit right after baby is born.  

Once you deliver your baby, we recommend waiting around 12 weeks before measuring yourself for a bra. The reason for this is that during those early weeks, your breasts are establishing their milk supply, so size fluctuations can be drastic – sometimes hour to hour – and you’re also healing. Your ribcage will likely contract after it expanded in pregnancy. So, after 12 weeks, you can expect that your ribcage and breast size will decrease. 

Measure yourself during pregnancy at least twice: 

  1. During the 1st Trimester: When you first need a Sleep Bra 
  2. During the 2nd Trimester*: When you notice the most growth 

 

Measure yourself postpartum once and then as needed: 

  1. Around 12 Weeks Postpartum, or once your milk production is established if breastfeeding: When your rib cage and breast size may decrease 
  2. As Needed:When you are going back to work and need a Pumping Bra, have a specific occasion you need a bra for, or if your bra no longer feels comfortable or supportive. Anytime you need to buy a new bra, we always recommend remeasuring yourself. 


SOLVING BRA FIT ISSUES

If you’re not happy with the fit of your current maternity or nursing bra, these tips will help you to identify the problem and correct it. 

The Bra Cups 

 A proper fitting cup should not gap or poke you.  

  • Are you spilling over and out of the cup? Try a larger cup size.  
  • Is the bra gapping? If you do not fill the cup, the cup will not lay smoothly against your chest. Try a smaller cup and/or band size.   
  • Is the underwire poking you? Try a larger cup size. 

The Bra Center Gore  

The Center Gore, the part between your breasts on an underwire bra, should rest directly on your sternum. However, if your breasts are naturally close together, the center gore may always sit away from the sternum.   

  • Is the center of the bra pulling away from your body? Your cups may be too small.  

The Bra Straps 

Both bra straps should fit snugly over the shoulders but should not be tight or act as your main support - this is the band’s job. 

  • Are the straps digging in? Loosen the straps. If this doesn’t fix the problem, your cups may be too small. Try a larger cup.  
  • Are the straps slipping off your shoulders? First, try tightening the straps. If they are still slipping off after you tighten them, try a smaller band size.    

The Bra Band  

A perfect fitting band should lay flat across your back, parallel to the floor. Motherhood Maternity bras are made with 3-5 hooks, depending on the style. When you first purchase your bra, it should fit on one of the middle hooks. This way, you can tighten or loosen the hooks as needed with size fluctuations during pregnancy and while nursing.   

  • Is the band inching up? The band needs to be tightened. Try a different hook, or a smaller band size.  
  • Is the band too tight? Try a looser hook or try a larger band size.

How do I care for my maternity and nursing bras?

The average lifespan of a bra is about 6 to 8 months. If you wear the same exact bra every day, the lifespan may be only 2 to 3 months. This is because repeated wear and washing can cause the fibers of the bra to lose shape and elasticity, which causes the bra to be less supportive.  

To extend the life of your maternity and nursing bras, we always recommend having at least four go-to bras that you can wear on rotation. One bra to wear, one bra to wash, one bra to sleep and one bra to keep on hand.  

Properly caring for your bras can also help to extend the life of your bras and keep their quality intact.   

NURSING BRA &MATERNITY BRA CARE INSTRUCTIONS: 

  1. Before machine washing, always hook the back of each bra and place in a lingerie bag. 
  2. Use the delicate cycle with cold water and a mild detergent. You may also hand wash.  
  3. Always hang dry your bras. Never put them in the dryer, as the heat will break down the spandex and the bra will lose support. The dryer can also cause damage to the material allowing any underwires to bend or even poke through and irritate the skin.
