Our measurements are taken from real-world use and are intended be used as a guide in selecting your size. In particular, over bust measurements will vary depending on your cup size and other factors. Remember, our bras are intended to stretch when worn to ensure a comfortable and supportive fit.

When measuring yourself take into account that your bust will increase as your milk comes in and decrease when your nurse. We commonly get asked if you should size up or go with what you normally wear.  We recommend you go with what you normally wear.  You want to feel supported and not have the bra be too loose once bub nurses.
