Oxxford Clothes Pure Cashmere Mens Sports Coat Blazer 42 Short Herringbone 3 Bt.

Measures 21.5 inches from the shoulder seam across the top to the other shoulder seam. It measures 31 inches from the top of the collar to the bottom of the jacket. It measures 23 inches from pit to pit. It measures 23 inches from the shoulder seam to the end of the sleeve.

There is no size tag so I am guessing 42 short. I normally wear a 42 regular and this fits everywhere except the sleeves.
