This fantastic 80s houndstooth jacket has no tag, but I would size it at medium. It has an oversized boxy cut, and is excellent over chunky sweaters and scarves. the white is slightly discolored. Measurements pit to pit 21 inches, waist 20 inches, full length from center 37 inches, top of sleeve 23 inches, inside of sleeve13.5 inches, shoulder span, 17 inches.
