My chest measures 39.5'', but every time I try on a 40R OTR suit jacket it seems too big. I wound up recently buying a 38R even though my chest is almost 40''
What gives? I have experienced this in multiple brands too. I guess my body type is weird? I always try to go from the shoulders and all the 40Rs looked too big in the shoulders.
That's 100% typical. Notice that if your waist is 32" a 32 trouser won't fit right either.
