Vtg Chaps Ralph Lauren Gray 2 Button Wool Blazer Jacket Sport Coat Worn Tag 38s?

Vtg Chaps Ralph Lauren Gray 2 Button Wool Blazer Jacket Sport Coat Worn Tag 38s? Rough unstretched measurements in photos. the size tag is worn and torn--it's hard to make out. The size looks like it starts with a 3 and ends with an s and the chest is roughly 20" across so I'm guessing it's supposed to be 38s--but please view photos for measurements to ensure proper fit. Good preowned condition. It's been hanging in a closet for a few years so does have a mild stale scent. Please see photos as part of the description.
