The printed bikini set includes a sarong as a third piece. That changes the outfit, but the sarong cannot correct a poorly fitting top or bottom. Treat the three pieces as separate decisions.

Fit the two swim pieces first

The straight-neck top lists S at 26-inch bust and 24-inch waist, rising to XL at 30 and 29 inches. Bottom waist ranges run from 22–26 inches at S to 27–30 at XL, with hip measurements of 26 to 30 inches. Compare each component with a swimsuit you own; the page does not explain whether these figures are relaxed garment sizes or body targets. If top and bottom suggest different sizes, ask whether mixed sizing is available before assuming the sarong will hide the difference.

Then ask for the sarong’s width, length and fastening or tie method, none of which appear in the chart. A waist wrap, shoulder drape and tied cover-up require different dimensions; choose after seeing the actual Multi print placement. The source states no padding, no underwire and lining on top and bottom, but does not document coverage or wet opacity. Its 88% polyester/12% spandex composition is not a measured stretch range.
