Is the St. Barth's One Piece good for swimming?

Yes for light swimming and lounging. The stretchy fabric and scoop neck stay in place, but the low back gives less support than a sporty one-piece.

How does it fit compared with other Monday Swimwear suits?

It runs true to the brand's sizing, with a high-cut leg and low back. Shoppers between sizes often size up for more coverage.

Does it have removable padding?

The suit is fully lined but has no molded cups or underwire. Bust support comes from the fabric and neckline alone.

What colors does it come in?

It is offered in Azure and a small set of other solid shades. Availability varies by color.

How should I care for it?

Hand wash in cold water and lay flat to dry. Avoid machine washing and tumble drying to protect the stretch.

Our take on the Monday Swimwear St. Barth's One Piece

The St. Barth's One Piece is Monday Swimwear's classic scoop-neck swimsuit, cut with a low back and a high-cut leg that lengthens the torso. It is made from a soft, stretchy nylon-spandex blend with a smooth, matte finish and is fully lined. It suits shoppers who want a minimal, flattering silhouette rather than ruffles, cutouts or hardware. Against similar designer one-pieces, it stands out for its clean lines and secure coverage up top, though the high leg and low back leave less coverage than a sporty suit.
