Women's One-Shoulder Bikini Swimsuit

Women's One-Shoulder Bikini Swimsuit

An asymmetric top with a single shoulder strap instead of two, paired with a standard moderate-rise bottom. The one-shoulder cut shifts support to one side, so the strap is reinforced more heavily than a standard two-strap top to compensate for carrying the full support load on its own.

This is a lower-coverage-on-one-side silhouette by design, so it fits differently than our symmetric tops even in the same nominal size — worth trying before assuming your usual Happari top size carries over directly. The bottom matches our standard moderate cut used across the core bikini range.

Sizing follows our standard bikini block, consistent across the collection, so if another Happari bikini fits you well this one will fit the same way. Ties on the top allow a small amount of adjustment beyond the base size, and if you're between sizes on the bottom, sizing up is usually the safer call. Rinse in cool water after chlorine or saltwater exposure and air dry rather than using a dryer, which is the fastest way to break down the fabric's stretch recovery over time — and avoid leaving a wet suit balled up in a bag longer than necessary, since trapped moisture accelerates color fade.

Every Happari piece is built on the same standard: fabric verified safe under OEKO-TEX Standard 100, organic fibers certified by GOTS, and a company held to B Corp accountability — not swimwear claims we're asking you to take on faith. If you like this cut, Leopard Print Bikini Swimsuit Set and High Waist Bikini Swimsuit Set are cut from the same fit logic. Ready to see the full lineup? Browse the Bikini Collection.
