Reposhing this jacket sold as a 1990s-era size medium, which I expected to run large on me. Rather this size medium fits more like a mens S/M. I am guessing it's a womens medium, but the manufacturer did not bother to point that out on the label. (Wouldn't it be great if we just abandoned gendered US sizing and went with the Euro numerical system that translates to metric measurements, so everyone knows what they're getting? Sadly, vintage will always be behind the curve!) Questions? Leave a comment below!
