Sizes & Back Styles

Sizing Approximations

We are a niche company designing our sexy swimwear with fitness inspired women in mind - therefore our suits are smaller than those of mainstream companies who design for all women of all sizes… We have no “Large bathing suits” per se. The size chart below is an approximation and since a size 5 varies from one company to another, we prefer to use measurements. For reference, we usually use size "small" in the photos. You can also e-mail, or type in the "comments section", the height/weight and chest/waist/*hips measurements in inches and lbs, and we will help suggest the best size for the suits ordered. (drop down menu for choosing sizes lists top size first/then bottom size)

*To measure hips, use a cloth tape measure around the widest part of the derrier. Hold as loose or tightly as you would want a suit to fit there. In the case of one pieces, we can add a third size (S,M,L) for torso length, separate from your top and bottom sizes. (For example: large top, large bottom, small torso length). We can sometimes make XL and XS sizes which may carry a custom charge.
