Gorgeous floral racer back tankini

Gorgeous floral racer back tankini. New with tags never worn. Racer top is black mesh. Sporty but sexy so beautiful sadly it does not fit me how I hoped otherwise I would be keeping it! Cups are removable with a securing strap. Base is 20 inches midway up 16 1/2 inches just under breast 16 inches and just under armpits 16 inches. Listed as XL fits more like a large.
