Joshua Trent Vintage Suede Beige 2 Button Blazer ‎ Mens 38R?

Gently preowned mens vintage Joshua Trent blazer. This blazer doesn't have a fabric tag but it feels like suede and says to treat like cashmere or any other fine fabric. It also doesn't have a size tag so please refer to the measurements. Shoulder to shoulder is 18". I listed this as a 38R but it really is unknown. The sleeve measurement is 24".
