Most of the other reviews indicated that this items runs a little small so we ordered a medium and, although it is a little big for my son, it fits him well enough with some room to grow. I would say that this item is somewhere between a small and medium. I'd say the quality is pretty good and it came with an extra button in case one comes off (as other have said). As a cosplay jacket, I think it will hold up just fine. It's probably not ideal for every day use.
