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 that ‘fits’ your body size. 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 that shows you your sister size – use the colours and numbers to help you match the sizes.

For example if you’re a 34D, you could also fit a 32DD or 36C

30 32 34 36 38 40 Example
A A A A A A A
B B B B B B A 36D is equivalent to 38C and 34DD
C C C C C C A 34DDD is equivalent to 32F and 36DD
D D D D D D A 34DDD is equivalent to 32F and 36DD
DD DD DD DD DD DD A 40DD is equivalent to 38DDD and 42D
DDD DDD DDD DDD DDD DDD A 34DDD is equivalent to 32F and 36DD
F F F F F F A 34DDD is equivalent to 32F and 36DD
