Fit Guide

When it comes to changes to your body during pregnancy and nursing, it’s important to find a bra that actually fits you. Comfort is key to not only your happiness, but your breasts’ health, too. Follow the steps below to measure yourself for a nursing bra.


For your rib band size, measure around your back and chest, making sure the measuring tape is placed above the breast tissue and parallel to the floor. The measuring tape should be snug around your body with no fingers under the tape. If you’re in between sizes, simply round up or down to the nearest even number.

For example, a measurement of 35.5” should round up to a 36, or 36.25” should round down to a 36”.


Next, for your cup size, place the measuring tape around the fullest part of your breasts and over your nipple area. Holding it looser than the rib band measurement, use your free hand to push the measuring tape down between your breasts to your chest. Take this cup measurement and subtract the rib band measurement. What’s left is your cup size, with each number equaling one letter (1=A, 2=B, 3=C, 4=D, etc).

For example, after subtracting 36 (rib band size measurement) from 40 (cup size measurement), a remainder of 4 equates to a D for a bra size of 36D.

All of the belly-to-babe styles are alpha-sized, so be sure to check each style’s size chart to determine which size you should wear.
