Our blue bikinis center on Deep Sea, a rich, saturated navy that behaves like both a color and a neutral. It's dark enough to be as versatile as black but with a little more warmth and depth, which is why a navy bikini tends to become the set people reach for most once they own one. Deep Sea flatters quietly. It doesn't demand attention the way a bright does, and it pairs cleanly with almost anything you'd throw over it.

A navy bikini is a genuine year-round, go-anywhere buy. It's understated enough for everyday swims at the pool or the lake, and polished enough to pack for a trip where you want one reliable set that goes with the rest of your suitcase. If you already own a black bikini and want a second set that isn't just more black, Deep Sea is the natural next step, familiar enough to feel safe and different enough to feel new.

Shop Deep Sea as separate bikini tops and bikini bottoms so you can get the fit right independently on top and bottom, rather than compromising on one to fit the other. That's the real advantage of buying separates: the top fits the way you need and the bottom covers the way you want, in the same navy. You can also carry Deep Sea across the rest of the range, using it as the calm anchor under a brighter top or over a bolder bottom.
