NWOT Stash David Bowie Heesen vintage Quilted Vest

Awesome grayish brown and green quilted vest with David Bowie quote on the back from Stash in NWOT condition! Super cool vintage look and great quote! The size on it is 50, and I'm not sure what that means? Fits like a large to me. It measures - pit to pit - 19 1/2" and shoulder to waist - 24 1/4"
