Shaping one-piece swimsuits

In a shaping swimsuit, the fabric, internal construction, and cut work together. Arena Shapewear uses stretchy Sensitive® fabric to provide shaping support. Internal Power Mesh adds support around the tummy and waist and helps smooth your silhouette. Built-in bust support provides support and shaping for the bust. Construction varies, with options including fixed pads, removable pads, and seamed bust support.

Arena Shapewear shaping swimsuits are made from soft, stretchy Sensitive® fabric that contours to your body and moves with you. The fabric contains LYCRA® XTRA LIFE™ fibers with enhanced chlorine resistance to help the swimsuit retain its stretch and shape for longer.

Arena Shapewear swimsuits with a low leg cut extend farther over the hips for more coverage. A medium leg cut has a more open leg line. The back design affects coverage and strap placement. Adjustable straps, where provided, let you fine-tune the length.

Seamed bust support and molded pads offer different constructions. Fixed pads are built into the swimsuit; removable pads can be taken out to suit your comfort preferences.

Compare your bust, waist, and hip measurements with the size chart on the product page. Shop online or try on swimsuits in store at Ludus to compare how different cuts fit.
