Swimwear Size Guide

Swim Fit Tips

You're in luck - we have many adjustable options! Our most supportive tops are : Montana, Dakota, Dottie, & Jena for One-Piece option! 

To take accurate measurements, use a soft tape measure—if you don’t have one, a piece of string and a ruler will work. Measure while wearing only underwear or nothing at all, avoiding thick fabrics or padded bras that can skew results. Focus on your bust, waist, and hips. Match your dims with the numbers in our size charts below.

We strongly recommend our Viv Top, Ace Bottom + Jolene One Piece as these have the ability to hug your curves in all the right places! 

We recommend staying true to size if the piece is adjustable, however size up if adjustability is not an option! 

Bikinis should fit like a glove. Let’s figure out your size so you can raise some hell in these suckers.
