Description

Our Boatneck Onepiece features a straight, high neckline and an elegant open back. The cut of this style together with two layers of fabric create a fit that feels supportive - allowing you to move confidently while being active in and out of the water. Additionally, it's designed with coverage where you most need it to help protect your skin from the sun. This style comes with a cheeky cut in the back, while the seamless construction creates a smooth, flattering fit that doesn't feel restricted.

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.
