Scarlette Black Ribbed Keyhole One Piece Swimsuit — a fitted black ribbed one-piece with a scoop neck, chest keyhole cutout, and a fully lined dual-layer nylon construction that holds its shape in the pool and translates directly to a bodysuit for everyday wear.

One of those pieces that doesn't announce what it is — at the pool, it's a swimsuit; tucked into high-waist trousers, it's a bodysuit. The keyhole cutout is the design detail that makes the transition feel intentional. Available in XS through L.

This one stopped us mid-scroll — a black ribbed keyhole that functions as both swimwear and a fashion bodysuit is the kind of dual-use piece that earns its place in a wardrobe beyond a single beach trip.

Ribbed exterior is 87% Nylon, 13% Spandex; interior lining is 80% Nylon, 20% Spandex — the dual-layer density keeps the black opaque, gives the bodysuit a structured feel outside the water, and holds up through pool use with equal ease.

Why This Piece Is Different

What convinced us to carry this piece was the dual-use construction. Most one-pieces are built for the water only — the Scarlette is built from the same ribbed nylon construction as the Monaco Bandeau and the Juliette Bralette Top, which means it holds its shape as a bodysuit just as well as it performs in the pool. The keyhole cutout is the detail that makes the bodysuit read as fashion rather than swimwear repurposed.

Style It Three Ways

1. Pool day: Wear with a minimal black sarong or wide-leg pants — let the ribbed keyhole cut do the visual work.
2. Bodysuit styling: Tuck into high-waist wide-leg trousers or tailored black pants, add mules and gold jewelry.
3. Resort evening: Wear under a sheer black maxi skirt with slides — the keyhole reads as an evening detail from the front.
