Bra Size Guide

Finding the perfect fitting bra is a piece of cake. All you need to do is find the band and cup size for your shape. Naturally then, the first step is to determine your body size, which is based on your ‘under bust’ size. The second step is to determine your cup size, which is based on your ‘over bust’ size and how it ‘fits’ with your body size (using our clever fitting matrix below).

Sister Sizing

Did you know that if you fit into one bra size, chances are you’ll fit into several other sizes too? Bra size doesn’t work the same way as clothing sizes as the band size varies with the size of the cup like a ratio.

If you go up a band size, you’ll go down a cup size and similarly, if you go down a band size, you’ll go up a cup size.

Here’s a simple chart to show your sister size – use the colours and numbers to help match the sizes. For example if you’re a 12D, you could also fit a 10DD (down a band size and up a cup size) or 14C (up a band size and down a cup size)
