One Piece

Shape, support and smooth in one piece swimsuits with Miratex® control, underwire options and swim dress coverage.

One piece swimwear should do more than cover. This collection brings Miraclesuit shaping to one piece swimsuits and swim dresses, with Miratex® control fabric, tummy-control construction, and necklines that draw the eye upward. Choose Oceanus for crossover draping through the bodice, Marais when you want swim dress coverage, or underwire styles like Escape and Avanti when bust support leads the fit.

How to choose one piece swimwear

Start with the shaping you want

If your first fit question is tummy control, begin with one piece swimsuits shaped through the bodice. Oceanus is a strong place to start: its V-neckline and crossover wrap-style front draw the eye upward, while diagonal ruched draping works across the front bodice for a smoother look. For a more dressed silhouette, Marais gives you a swim dress shape with a V-neckline, twist front detail and a fit-and-flare skirt. It is a useful choice when you want one piece coverage with shaping through the waist, hips, thighs and backside.

Choose the bust support first

A beautiful one piece starts with the bra. Oceanus offers soft cup bra construction, while Escape and Avanti offer underwire support. An Avanti colorway also offers underwire with removable pads, helpful when you want more structure through the bust. If you are choosing by cup and support, compare the suits in Best One-Piece Swimsuits With Support. For a larger cup fit, One Piece Swimsuits for Big Busts keeps the focus on support before you choose print, neckline or coverage.

Decide how much coverage feels right

A classic one piece gives a clean, sculpted line through the torso. Look for V-necklines, crossover fronts and draped panels when you want the suit to elongate the upper body and smooth the midsection without adding bulk. A swim dress changes the proportion. Marais adds a short skirt over the one piece silhouette, with coverage through the hip and thigh area. Use it when you want the ease of a one piece with a little more movement over the lower body.
