This is a really nice find. Its a soft knit on the top and cotton shorts on the bottom.

The top portion is lined and feels like a soft jersey knit.

The straps are adjustable with 3 settings and a buckle.

It measures 36" bust, 28" waist, 36" hips and 23" long from the armpit.

Machine washable, its a polyester blend.

Super cute!
