Mid 80's 615 SZ 42
Does anyone know what the approximate measurements would be for a Mid 80's 615 size 42? I'm looking at buying one and need to know if it'll fit. I'm 6'1 185lbs and typically wear a 40 suit coat, and like all of my jackets to have a slim or tailored fit to them. I know they often say to size up in perfecto's but I'm not sure if that same rule of thumb goes for jackets from this time period. Thanks for your help i this matter.
