Swimsuit bottom with skirt

Black skirted swimsuit bottom. Size tag is missing, but I was told it is an XL. Polyester and Spandex. Elastic waist measures 18” across unstretched. 14” from top of waistband to bottom. The back at the middle is approximately 2” longer than the front. Looks in great condition and possibly never used, no snags or stains or ripped seams. White paper slipped in under the slashed seam to demonstrate this feature of the swimsuit.
