Maternity and Nursing Sports Bra: How to Pick Your Fit

Quick answer

Choose a maternity nursing sports bra by measuring your underbust and full bust now, then selecting a size that accommodates your current fit with room to adjust. Prioritize adjustable features like hook-and-eye closures and extender compatibility, and verify one-handed nursing access before you commit.

Step-by-step fit process

1. Measure your underbust and full bust: Use a soft tape measure snug around your ribcage and around the fullest part of your bust. Round to the nearest whole number and note both measurements. Measure at the end of the day when your bust is largest for a more accurate fit.
2. Check the band fit first: The band should feel snug but not tight, and you should be able to fit two fingers under it. Try it on the loosest hook to leave room for ribcage expansion. If the band rides up, go down a band size; if it digs in, go up.
3. Test cup coverage and support: Bend forward and side to side. Your breast tissue should stay fully inside the cups without spilling over or leaving gaps. The center gore should lie flat against your sternum. Cups that wrinkle or gap mean the cup is too large; spillage means it is too small.
4. Verify nursing access: Practice opening and closing the nursing clips with one hand. The closure should release easily but stay secure when closed. If you struggle with two hands, the bra will be frustrating during night feeds.
5. Move around to test stability: Jog in place, reach overhead, and simulate a workout movement. The bra should stay in place without riding up or shifting. If the bra moves, try a smaller band or a style with more structure.
6. Re-check fit as your body changes: Re-measure every 4–6 weeks during pregnancy and again around 6 weeks postpartum. Use a bra extender if the band becomes tight before you are ready to size up. A bra that fit at 20 weeks may not fit at 35 weeks; adjust as needed.
