One-Pieces

All Swimwear Bikinis One-Pieces Kids Men

The designer one-piece is having a moment — and Swimwear World stocks the best of them. Sculpting maillots, plunging necklines, cutouts, surplice fronts, racerbacks, and classic scoop-necks from the brands defining contemporary swimwear.

Shop by silhouette

Plunge one-pieces for vacation glamour, one-shoulder swimsuits for sculptural lines, square-necks for clean modern lines, surplice and wrap fronts for figure flattery, cutouts and monokinis for statement looks, and classic scoop-back maillots for everyday wear.

Shop by fit

Sculpting compression-fabric one-pieces from Vitamin A and Robin Piccone, embellished and hand-finished pieces from Agua Bendita and Beach Bunny, and runway-inspired silhouettes from Devon Windsor.

Layer it up

A great one-piece doubles as a bodysuit under shorts or a skirt — shop our cover-ups and resort dresses to complete the look. Free US & Canada shipping.

One-Pieces — Frequently Asked Questions

Very. One-pieces offer smoothing, support, and versatility. Plunge necklines elongate, square necks give clean modern lines, surplice and wrap fronts flatter the midsection, and cutouts add a statement without sacrificing coverage.

Many do. Robin Piccone uses compression fabrics and structured construction for a sculpting, supportive fit, and Beach Riot offers padded one-piece styles. Cup and support details are listed on each product page.

Yes — a great one-piece doubles as a bodysuit under shorts, skirts, or trousers, making it one of the most versatile pieces in a vacation wardrobe.

We carry designer one-pieces from labels including Beach Riot, Robin Piccone, Agua Bendita, Beach Bunny, Devon Windsor, and Maaji — from minimal maillots to sculpted, statement styles.
