I actually came to ask the exact question, so I appreciate the very helpful advice (as well as Steve Smith's). I'm in the same boat as the OP of the question... I'm a 40" chest and 18" shoulders... can anyone recommend some slimmer cut sportcoats/blazer brands to search for on eBay? I've started with Borrelli, Corneliani, PRL, but would appreciate any other input. Y'all are the best.
