      The Sienna is a universally flattering suit, paneled on the bias to follow the slanted one-shoulder neckline. The color-blocking results in a beautifully proportioned silhouette, including the illusion of a high waist and longer legs. Removable pads and a cutout back complete the picture on this graphic one-piece design.

Fabric & Care

91% Nylon 9% Spandex. Custom-created for us in France, this jacquard stands out as a luxurious choice for beachgoing and beyond. A closer look at its tactile surface is required to appreciate the raised floral relief, which mimics the look of fine embroidery. The loom-weaving process is intensive, resulting in excellent stability, stretch and lovely gradations in the fabricǃÙs soft texture and tone.

Hand wash cool water. Do not bleach. Do not tumble dry. Flat dry. Do not iron.
