This is a sweatshirt crop top by "Scotty" Color - gray and wording on the back says "Go Away Monday" There is no size noted on the label so I have to go by the measurements below: Length - 18" Armpit to armpit - 22" flat across Shoulder to Shoulder - 21" Sleeve length - 23" Just an approximate guess that this is a medium or large Cotton or cotton blend
