Mark Shale 100% Cashmere Double Breasted Blazer Size 40R

The softest fabric in gorgeous condition would be perfect on a man or a woman. The interior of pocket tag says 100% Cashmere and I believe it says 40 R. Please go by these measurements just in case it has been altered or I misread that. Approximately 29” from shoulder to hem, 20” across chest armpit to armpit, 24” sleeve from shoulder to hem, 17” across the back shoulder to shoulder.
