ERES Les Essentiels Cassiopee Bandeau Swimsuit

View On Net-a-Porter

A heritage brand, ERES has been around for 40 years and is known for its sizing expertise. The label's bandeau one-piece suits are made of a soft, smoothing fabric called peau douce, which translates to “smooth skin,” and mirrors your glowing complexion. We love that this comes in a palette of hues; plus, there’s no need to worry about hard-to-hide tan lines. The U-ring design seamlessly secures your top and shapes all curves. After trying this on, our take is that it’s  “smooth and comfy." However, going up a size might be necessary to avoid discomfort in the chest area.
