Hello all. I've been scouring eBay for a couple weeks now looking for a vintage cafe racer jacket and had a quick question about sizing. If my actual chest size is 42" what would be a good jacket chest size to look for? I'm sure it depends a lot on personal preference but if I want a simmer fit would a 42" chest size work? I'm thinking that would be way too tight but am looking for suggestions. It seems my other jackets have at least 3-4 extra inches in the chest. Thanks for all the help.
