Fit is very important to us and therefore our tops are cup-sized, instead of following the standard XS-XL scale, which assumes small back sizes have a small bust and vice versa. We refer to sister group sizing of 1-6, where sizes are grouped based on the cup volume that they cover, which is ideal for swimwear due to the stretch of the material and adjustable functions. For example, if you are normally a UK 32DD then you should opt for size 4, this will also fit UK sizes 30E, 34D and 36C, which have the same cup volume. To work out your sister size, you can go up a cup size and down a back size and vice versa.
