The size tag is missing though the chest measures right about 50 inches across. I would say that’s probably suitable for about a 46 as you want it to be a little oversized, but please refer to all pictures for details and measurements. Overall condition is very good made in USA no flaws or issues besides the inside seam where the sleeve meets in the lining by the shoulder has a 1 inch tear at the same. You can wear it as is with no problem at all or it would be a very easy fix if you choose.
