Why an adjustable nursing bra is worth it

Your body is not the same every day, and that is especially true while you are pregnant, feeding or recovering postpartum. Adjustable bands and straps let you fine-tune the fit as your body changes, so your bra keeps supporting you through it.

How should a nursing sports bra fit?

Four quick checks. Not sure of your size? Use our Size Guide.

1Check the band. It should feel snug and sit level around your ribcage. Use the adjustable back to fine-tune it.
2Check the cups. No gaping and no spilling at the top or sides.
3Check the straps. They should sit comfortably without digging in.
4Compare with our models. Every product page lists what our models wear and their usual bra size, so you can compare with your own.
