Vntg black leather jacket, unisex?

vintage excellent condition leather jacket from brand Chessking size 38 (EU sizing most likely, but pitentially Asian) fits me with a little room and I'm usually a small to medium depending on cut. internal vest is fully removable but also allows this jacket to be worn across multiple seasons. front and back zipper detailing DOES unzip, but mostly cosmetic. however, it does add a small amount of extra room/expansion no noted flaws or imperfections ****** closet
