The double-strap tied swim dress combines a plunge neckline and slit with a dress-length body. Its single S–2XL size must settle both bust fit and where the slit falls; a longer hem alone cannot determine coverage.

Place the slit on your reference

Take a swim dress or fitted dress you own and measure from its upper edge to the hem. The listing’s lengths run from 27 inches at S to 30.4 at 2XL. Ask for the exact starting point of that length and for the slit start measured up from the hem. Mark both on your reference garment, then compare its bust and waist with the selected row: S is 29.3/25.4 inches, while 2XL is 37.1/33.2. If one point fits and the other pulls, a tie may not fix the underlying circumference.

The page states removable pads, no underwire, high stretch and 90% polyester/10% spandex. It does not show whether the double straps adjust independently, how the slit opens when seated or whether the fabric remains opaque when wet. Confirm the selected Black or Dark Navy construction with a current side and back image rather than inferring those details from the name.
