This is an Oleg Cassini nylon jacket. It's a US size L. I bought it over 10 years ago at a vintage clothing store while I was in the US. ＜Notes＞ ・The elastic at the cuffs is stretched out. ・There is visible staining around the collar. There is no size tag, but it's about the size of a Japanese XL. If you would like to know the detailed measurements, please comment. Please purchase only if you understand that this is a used item and has been stored by an individual.
