Gently used, no noticeable flaws. No fabric details but feels and appears like polyester. Blue scoop-back onsie singlet wrestling suit with contrasting white trim. Lightweight stretch fabric for comfortable movement. Sporty silhouette ideal for workouts or layered looks. Would be great as an eclectic outfit for a festival. Last pic with back of model is not same singlet, but similar and shows how it could be styled wearing under a skirt and possibly baggy jeans. Size medium. Please see approximate measurements below to determine your fit. All laying flat. Very stretchy. I normally wear a size 6 dress, 28 pants and this fits me fine, though very fitted. Someone who is a small will find a bit more wiggle room. 16” across waist 27” long
