Pregnancy is a time of incredible change—and your bra drawer needs to change with you. From the first trimester to the third, your breasts will grow, change shape, and become more sensitive.
Here’s what you need at every stage.
First Trimester (Weeks 1–13)
What’s happening: Breast tenderness, early growth, sensitivity
Bra needs: Soft, comfortable fabrics; no underwire (can be uncomfortable during sensitivity); light support; stretch to accommodate early growth.
Best styles: Soft bralettes, wireless bras, cotton bras
Second Trimester (Weeks 14–27)
What’s happening: Significant breast growth, changing shape
Bra needs: More support; adjustable features; room to grow; comfortable for all-day wear.
Best styles: Maternity bras with adjustable bands, wire-free support bras, seamless stretchy styles
Third Trimester (Weeks 28–40)
What’s happening: Maximum breast size, preparing for nursing
Bra needs: Maximum support; nursing-ready features (if planning to breastfeed); comfort for the final weeks; room for continued growth.
Best styles: Nursing bras (even if you haven’t started nursing yet), full-coverage maternity bras, sleep bras for overnight comfort
