Little Creative Factory asymmetric leotard

Little Creative Factory asymmetric one shoulder leotard - this is so unique and trendy ! We wore as a dance leotard but I saw it online also listed as a bathingsuit so I think could be either ( the material is double lined soft cotton , not the typical bathing suit material) . I realized when looking for a tag ( there is no size tag just little sewed on plastic square tags shown) that this is double sided ! Could wear with dark grey facing out or the lighter gray cooler however please note listing as GUC because the lighter grey size shows a light stain on the back ( see picture ) we only ever wore with the dark gray facing out. No size tag but fit us 5-7
