Description

Our Boatneck Onepiece features a straight, high neckline, an elegant open back, and a metal clasp at the neck for easy wear and a secure fit. The seamless construction creates a smooth, flattering silhouette with medium to cheeky coverage.

Crafted with two layers of fabric for support and comfort, this onepiece feels soft yet structured. The outer layer has a terry-like texture with a subtle stretch, while the reverse side reveals our smooth signature fabric in muted terracotta — fully reversible and designed to move with you.

Fit note from Mimosa, our designer 💌

Our Sienna is a gorgeous texture fabric that we absolutely adore. It is to note that the fabric is more stretchy than our usual fabric, and therefore, the fit is naturally a bit more soft. We don't recommend sizing up. If unsure, you can rather size down.
