Ay, there's the rub. My Kamakura (40-84 Tokyo Slim) is pretty tight across the shoulders and chest. I'll probably order a size up (41-85) to compare but anticipate that'll be tight on the chest as well. Looks like it's just the way these shirts are cut. And there's nothing in their fuller cuts that comes close to those neck/sleeve measurements. I mean, all things considered this shirt is a fantastic intersection of price and quality - certainly the best I've found so far - but if it doesn't fit there's no helping it.
