Here's the deal: I bought this in Oslo, Norway in 1996. Used it for a couple of seasons in Europe. The size on the tag says 50, that is a Norwegian size. A little extra room because it is an overcoat and would be worn over a shirt and sweater or dress coat.
The measurement from the top of the should seam to the cuff is exactly 23 inches. I wore it as a banker and always got compliments. I will throw in the red wool scarf (pictured) for free.
