One-Pieces

You'll find one-piece swimsuits designed for comfortable coverage, flattering fit, and easy vacation packing.

Quince one-piece swimsuits are made from Italian fabric — the same high-quality material used by luxury swimwear brands — at a fraction of the price. You get a sculpted, supportive fit without compromising on feel or durability. Pair with one of our swim cover-ups for a complete beach or pool look.

A one-piece suits situations where coverage, support, or a polished single-silhouette look matters — vacation poolside, beach club lounging, active swim, sun protection across the torso, or moments when you want one decision rather than coordinating two pieces. Bikinis suit situations where mix-and-match flexibility, separate fit between top and bottom, or all-out sunning matters. Many shoppers own both — the one-piece for vacation outfits and active days, the bikini for pure beach days.

Most run true to size based on bust and torso length. Sculpting styles fit close-to-body with built-in compression — true to size; size up only if you prefer less compression. Full-coverage styles fit close to body with more fabric coverage. Quince one-pieces are designed with adjustable straps on most styles for shoulder-to-bust customization. If you have a longer torso, look for adjustable-strap styles for the best fit through the body.

Rinse with cold fresh water immediately after each wear — pool chlorine, salt water, and sunscreen break down swim fabric over time. Hand wash cool with mild detergent, or machine wash on a gentle cycle in a mesh laundry bag. Lay flat to dry — never wring out, never tumble dry. Avoid sitting on rough surfaces while wet (concrete pool decks can pill the fabric). The compression construction in sculpting one-pieces holds shape well across many wears when cared for this way.
