We worked hard to develop a sizing system for a smooth, stress-free shopping experience — without compromising on fit. Our dual sizing system includes:

A tailored bikini + bralette size chart, designed to support fuller busts across band and cup sizes (28F–40KK)
An international bottoms guide to help you find your perfect fit wherever you are in the world.

Every size in our collection has been tried, tested, and approved by fuller bust women of different shapes and body types. We’ve done the hard work so you don’t have to second-guess your size.

Our current range includes sizes XS to XL across tops and S to XL across our bottoms.

Use the charts to confidently find your match — and feel good in every piece.
