Size L 9527… Closer to a size M 527, if you look at the charts (which I did for once). Bit more room in the shoulders, other than that the same golden cut (imo). Tight but agreeably comfortable. Sweater underneath. Cuffed sleeves.
This bastard has wrecked 2 coat hangers. One was a plastic hanger with a metal screw-on hook…ripped the hook right off the plastic. The other hanger is a thick plastic one that now looks more like a diamond than a triangle. Jacket's a beast!
