The cutout contrast swim pants list both a waist measurement and a separate “Waist Stretch Amount.” Those are not self-explanatory labels: the second may be an extended circumference, an extension amount, or something else. Confirm the measuring method before using it to choose a size.

Audit the two waist columns

At S the chart shows waist 25.98 inches and stretch amount 27.56; at XL it shows 32.68 and 35.43. If the second number is a maximum circumference, the differences are 1.58 and 2.75 inches, but the listing does not say so. Do not add those numbers together as if “amount” were extra fabric. Compare a comfortable pant at waist and hip—S hip is 34.25 inches, XL 42.52—and ask the seller for relaxed and gently extended flat-waist measurements.

Bottom length runs 41.73 to 44.09 inches, so check how that length is taken before planning a shoe or poolside hem. The source lists a cutout, moderate stretch and 100% polyester, but gives no cutout position, lining or drawstring construction despite the name. Request front/back images of the selected Multicolor option. No chlorine, UV or compression performance is established by those labels.
