The black one-shoulder swim set combines a ruffled asymmetrical top with a ruched high-waist bottom. Its S–2XL chart lists bust, waist and hip numbers, and the top has removable padding with no underwire. Those facts help narrow a size, but they do not tell you where the single shoulder sits or how high the bottom rises on you.

Use three fit points, not one letter

Measure your bust, waist and fullest hip, then compare all three with the same chart row. The published S row lists 32, 25 and 35 in; 2XL lists 40, 32 and 41.5 in. If your three measurements point to different rows, ask for the finished top and bottom dimensions rather than assuming the stretch label resolves the gap. The source does not clarify whether its chart uses body or garment measurements, so confirm that before calculating ease.

Check shoulder and rise separately

For the one-shoulder top, ask for a flat photograph of the selected size and a measurement from the top edge to the shoulder point. A strap that sits well on one shoulder shape may sit differently on another; the page provides no strap width, adjustment method or support test. Removable padding lets you choose whether to use the pads, but it does not establish a fit or support level.

“High waist” describes the bottom style, not a measured rise or coverage area. Compare the rise and leg opening of a swim bottom you like and ask for the same dimensions on this one. The listing says the body is lined and gives 83% polyester and 17% spandex, without a measured stretch range. Check the size and Black option in the cart; use the chart as a starting comparison, not a guarantee of coverage while moving.
