Let us help you take the guesswork out of finding your maternity size and help you look and feel great!


Comfort is key. Our line of intimates perfectly adapts to your changing needs both during and post-partum. Our maternity bras with nursing function provide comfort and support as you transition from pregnancy to nursing. Use the below instructions to find your size.


You should buy your maternity bra at the start of your second trimester. Please visit our store for a personal fitting.


Wearing a non-padded bra, wrap the tape around your bust over your bra at the fullest point. Keep the tape level around the back and fairly loose around the body.


Wrap the measuring tape tightly under your bust around your rib cage. Be careful to keep the tape level from front to back. Exhale fully, pull the tape tightly around your body, then round your measurement up to the nearest inch. Add the correct number of inches to the measurement using the below.​

RIBCAGE UP TO 34" 35 - 38" 39" +
EVEN NUMBER + 4" + 2" + 0
ODD NUMBER + 5" + 3" + 1

Example: 31" ribcage + 5" = 36 band size


After measuring, subtract your band size from your bust size. Find that number on the chart below to get your cup size.

Example: 40" - 36" (Band) = 4" (D)

Your Bra Size is your band size plus your cup size. Example: 36D
