This is a costume of the Uma Musume Training Academy uniform. It's a two-piece set, which really suits those with a "bone structure" body type. Those with a bone structure, this is a great deal! It really makes you look good. It's a set including the uniform, ribbon, and knee-highs! The size is listed as M, but it's made by a manufacturer that runs small, so it's probably closer to S-small M size. It fit me perfectly, and I'm 151cm tall and of average weight!
