A maternity sweater is one of the most important pieces of your maternity wardrobe, and the easiest to wear are 3/4 sleeve maternity sweaters. If you're pregnant through more than one season, this maternity sweater will get you through. For warm weather, wear one as a maternity cardigan over tanks or tees. For cooler weather, wear a v- or crew neck 3/4 sleeve maternity sweater with your favorite maternity pants.
