Nursing & Maternity Bra Size Guide

first step | band: 

The bottom edge or band of bra should be parallel to the floor. If it rides up, tighten the back hooks, or you may need to buy a band size down (ie 34 to 32). Cutting in? you may need to go up a band size (ie 34 to 36). Our bras come with 6 hook settings for extra extension to give the most flexible fit as you grow and change.

(ie 30-38) Start with your underbust measure so we can get your band size. Place a measuring tape firmly around your ribs under your bust. Relax your arms down and breathe out to get the smallest measurement. Note it down.


1st trimester - Start at the 2nd - 3rd hook from the tightest, you can adjust this as your ribcage expands.  Shop a few nursing bras now, you can wear them again when you and bubs have settled into feeding and your boobs have settled.
2nd trimester - Move to the 3rd - 5th hook so there is still enough room to let it out during the 3rd trimester and bring it back down after birth. You may bust out of these cups in the 3rd trimester, but don't worry, this bra will be handy for the middle stages of breastfeeding.
3rd trimester - During the last several weeks of pregnancy extend to the 5th - 6th hook. You may outgrow the cup size, however it can be used again during your established breastfeeding journey.
after baby arrives - Adjust band to make it smaller as needed. Your milk coming in may expand your cup size! Lets discuss that next...

second step | cup:

The bust should sit in the cup without gaping or spilling over. Check the straps first, then if your spilling over you may need to buy a cup size up (ie 34DD to 34E). Gaping? You may need to go down a cup size (ie 34DD to 34D). The depth/fullness of your cup will change the most during pregnancy, you may increase 1 cup size by the 2nd trimester and a 2nd cup size by the end of your pregnancy. That means 2 - 3 changes in bra size throughout pregnancy and breastfeeding...    

find your cup size (ie D-J)
To measure your cup size, its good to do this between feeds and wear the best fitting bra you have, preferably with a wire and no foam cups to get the right size. Keep the tape loose and measure around the body at the fullest part of the bust. Write down the number.
