I am between a Small and Medium (6-8) and find this THE perfect fit for what's usually a super annoying middle ground for jackets and sweaters. I live in LA and have paired this comfortably with just a tee underneath, though there's just enough wiggle room to layer over a knit or hoodie, as I have in London during the chilly Autumn months. I'm listing this here because black isn't really my fav colour at the moment, but in my opinion this jacket has only grown more beautiful with time and wear!!! The leather is in visibly immaculate condition, so much more soft and flexible than when it was right off the rack. It's an Acne Studios leather jacket - you can see the quality of leather amd design from a mile away.
