Designer’s Notes

FINAL SALE. This item can only be returned for store credit or exchange.
The Chikyu One-Piece Swimsuit in Mosaico is a refined, best-selling silhouette designed to balance structure, coverage and modern simplicity. With a clean square neckline and a low-cut back, it offers a confident, sculptural look that feels elegant and understated.

Designed with wide, supportive straps, Chikyu provides a secure fit that stays in place while swimming. The high-cut leg subtly elongates the silhouette, while the fixed tie belt defines the waist and adds a considered finishing touch.

With medium coverage, a built-in padding pocket with removable pads, and a fully doubled construction for sheer protection, Chikyu feels flattering and supportive both in and out of the water. Finished in the neutral Mosaico shade, it’s a versatile one-piece designed for effortless summer wear.
