Size Med, but these sizes run small on vintage items. Measures 21 inches across front from armpit to armpit. It's 25 inches long measured down center back. Sleeves from shoulder top of sleeve to cuff are 25 inches. In very good condition; clean, no marks or snags. No fading, no stains or discoloration. All bottom edge finish and cuffs retain good stretch. There was a small loose thread in the upper right shoulder area that was professionally repaired by the tailor (see photo).
