Nursing Bra Sizing

We know that finding a maternity bra feels like an impossible task. That's why we've made it simple with these helpful tips:

1. Order a bra at least 1 cup and band size larger than your pre-pregnancy bra. Example: If you are originally a 38C, try ordering a 40C.
2. Use the "Sizing Help" tool on our nursing bra pages to calculate your recommended fit. The "Sizing Help" tool will recommend two sizes. If you can't choose which one, order both! We offer free returns and exchanges so you never have to leave your home to find the best fit.
3. Reach out to a Fit Stylist!
