Size Guide

Sizing is an important part of the GUD Swim design process and our pieces are thoughtfully created so women feel beautiful and confident in their swimwear. Each woman has a unique body shape and different personal preferences for how each style sits on their body! We have included a detailed size guide along with our models measurements and size preferences, to help you find your perfect fit.
