Our black bikinis are the anchor of any swim wardrobe, the set you reach for when you want to look pulled together without thinking about it. Sea Urchin is our take on black: a deep, true, saturated shade with no washed-out cast, so it reads as a clean, classic black both in and out of the water. It holds its color wear after wear, which matters more with black than almost any other shade, since a faded black bikini is the first thing that makes a suit look older than it is.

A black bikini earns its place because it does the most with the least. It flatters across skin tones, it never competes with a printed cover-up or a bright sarong, and it moves easily from a morning lap swim to an afternoon on the sand to dinner with a slip skirt thrown over it. If you're building a capsule swim wardrobe, Sea Urchin is the first set to buy and the last one you'll retire.

Because every style is sold as separate bikini tops and bikini bottoms, you can size each half independently, which is how a bikini is meant to fit. Take one size on top and another on the bottom if that's your body, and you'll get a set that actually stays put. It also means you can mix and match: pair a Sea Urchin top with a brighter bottom, or a black bottom under any top in the range, and the black does the grounding work.

Shop the full range of black bikini tops and bikini bottoms, and build the set that fits the way you want it to.
