J.crew Chambray Shirt, Size S/M

J.crew Chambray Shirt, Size S/M. Never worn, fit true to size on me and I usually wear size M. Length approx.28”, bust 20” lying flat, sleeve 23”. 100% soft cotton. The label reads “ Japanese selvedge chambray ”. It is a very soft and comfy cotton material. The size marked as SM, I think it fits M better . No lowballing please. Thanks!
