Celia Cobalt Blue One Shoulder One Piece Swimsuit — an asymmetric one-shoulder one-piece in electric cobalt blue Eco Crinkle fabric with high-cut legs and a silhouette that molds to the body through the 4-way stretch construction.

The one-shoulder cut makes every angle the good angle — open at the back from the shoulder asymmetry, high-cut at the leg, saturated cobalt throughout. One piece that actually has a point of view. Available in XS through L.

This one came to us from Beau Swim in a Eco Crinkle drop — the recycled nylon crinkle texture is the detail that sets it apart from every other one-shoulder on the market. It looks different because the fabric is different.

Eco Crinkle — 92% Recycled Nylon, 8% Elastane — the crinkle is structural, woven into the fabric rather than applied. Soft, quick-drying, with 4-way stretch that molds to the body and fully recovers after every swim.

One of the more distinctive pieces in our swimwear collection — wear it as the anchor of a full vacation outfit with a linen cover-up and slides.

Why This Piece Is Different

This one passed every test we ran. The one-shoulder swimsuit has been done — what separates the Celia is the Eco Crinkle fabric. 92% Recycled Nylon with a structural crinkle woven into the construction means the texture is permanent, not a wash-treatment that fades. The cobalt in this fabric has a depth that most recycled performance textiles don't deliver.

Style It Three Ways

1. Classic beach: Wear with a white linen sarong wrap, straw hat, and simple leather slides.
2. Resort pool: Style with a sheer mesh cover-up and gold hoops — the cobalt needs nothing else.
3. Pool to dinner: Pair with wide-leg tailored trousers in cream or white, mules, and minimal jewelry.
