Women's Black Swimwear

For competitive laps, pick a streamlined one-piece like the Speedo cross-back one-piece that uses hydrodynamic fabric to reduce drag by 20 to 30%. Streamlined seams and compression help minimize resistance during training and races.

Rash guards with UPF 50+ and quick-dry polyester, such as the O'Neill rash guard, block sun and shed water during surf sessions. The UV-protective fabrics and reinforced stitching also increase durability for frequent use.

Underwire and balconette tops offer structured lift and are better for larger busts, while triangle and bandeau styles flatter smaller busts but can shift in the water. Styles with wider bands and reinforced stitching, offered in sizes from XS to 3X, provide the most reliable support.

Swim dresses and high-waist bottoms provide extra thigh and midriff coverage, making them a good choice for modesty and relaxed water activities. Ruched or contoured panels add flattering shaping, and options like the Hydro Flask high-waist bikini in recycled nylon help create an hourglass silhouette.

Removable cups let you customize shape and support, while adjustable ties give a tailored fit and reversible prints double your styling options. In 80% nylon/20% spandex blends with reinforced stitching, those features still hold up to frequent wear.
