I wore this once for an Izaya Orihara (Durarara!!) cosplay. There are no noticeable stains and it doesn't feel used, but it has been stored in a dark place for several years, so please refrain from purchasing if you are concerned. *Jacket only. Regarding the size, from a layman's perspective, it fits me perfectly, and I am 155cm tall. It should fit slender people up to 160cm. Shipping will be via Rakuraku Mercari. Instant purchase is OK.
