Some of our styles carry India / UK cup sizes and some carry US cup sizes. The two names on the same row are the same size - for example 34E and 34DDD are one size, not two.

Cup steps are 2.5 cm (1 inch). Your under bust decides the band size, and the difference between your top bust and under bust decides the cup.
