Find your perfect Peachaus fit

Our bodies change from month to month, which is why finding the right bra size is so important.

We’ve given bra sizing a modern update by making our underwire bra range fluid fitting, meaning you can comfortably size up or down depending on how you want to feel. Your body, your mood, your fit. Simple! More on our fit philosophy here.

Finding your Peachaus fit is super easy.
Your band size is your dress size (S, M L), and your cup size is the measurement around the fullest part of your bust.

Watch the video below for a more detailed guide to measuring for our underwired bras.
