Even for XL it says 16 inch shoulders. Even my tight jacket has 17.7. Do you think they might have 'undermeasured' here? By the way, I remember your being interested in the 1915 Levis. Could you locate a pair? I was wearing mine the last few days and kind 'rediscovered' how nice they are. Nice cut, not too slim, not too wide, not too high rise, neither too low. Nice details like the different pocket stitchings and a special denim.
