Inserts Sizechart
Our sizing chart is very accurate, so please follow it for the most accurate sizing. As a VERY general guideline for swimsuit tops an XS would be our A-Cup, Small would be our B-Cup, Medium would be our C-Cup, and Large or XL would be our D-Cup. If you are in between cup sizes and buying for a swimsuit top, we advise sizing down to the smaller cup. If you are in-between sizes and buying the inserts to use in a sports bra, size up to the bigger cup.
