Sizing is a FAQ around here so here's a chart to help you out!

 

Size       Cup Size        Ribs            Bust

 XS                  A                < 27"              < 31"

        S                   B              28" - 30"          32"-34"

 M                   C                 > 31"               > 35"

 

We carry sizes XS / S / M and that loosely translates to A cup / B cup / C cup but it comes down to your fit + support preferences. Mediums accommodate some D + DD so make sure to check the support level of the product listing. If you're still uncertain or you fit in 2 size categories, include your measurements in your order notes and we'll make it custom fit!
