Do you haz odd proportions? I don't have small arms and I find that their oxfords fit me fine. I tend to favor the regular fit over the slim fit, unlike most on here, since I wear it under a knit anyway and it has a bit more room in the shoulders /arms and some more length.
Not really. I wear a 15.5/16 shirt with 33-34 arms most of the time. I think I might have tried their slimmer fit, but I tried like 3-4 shirts. If I flexed at the elbow, the fabric would pinch up, i.e. it would probably rip there pretty fast. None of my other shirts do that.
I wear a 40R jacket with about 25 inch sleeves, 18.5 shoulders, and 21 ptp. Their jackets in a medium were too tight in the chest and the L's had sleeves down to the knuckles.
I just got a lands end jacket from work (with dept logo etc) and same story there. Small fits me pretty well but too tight on chest. I got a medium that's better on the chest but everything else (waist, sleeves, etc. are way too long).
I'm 5'10 and weigh about 160. I do lift though, so it could be that, but I'm still pretty small by lifting standards since I've had back surgery 2x and don't lift heavy anymore...
