ホルターネックワンピース水着（バックオープン、ウエスト結び）

I love how the high-waisted design gives a retro feel while keeping everything secure, and the waist tie adds just the right touch of detail. It fits true to size and stayed in place during a full afternoon of swimming.

The open back on this suit is so flattering, and the high waist gives me extra confidence at the pool. Fabric dries surprisingly fast, too.

The waist tie is such a clever detail, it cinches perfectly without being too tight. The open back makes it feel both supportive and sexy at the same time, which is rare for a one-piece.
