I just returned the LE Canvas oxfords I've had for a year due to an unfortunate bleaching accident (should've read the label more carefully). I decided to upgrade to BB (never liked the LEC's small collar). I tried on a full-cut 15Â½-5 shirt at a thrift store, and it fit right in the shoulders and neck. So I ordered an extra slim fit 15Â½-33, but the chest is a little tight (or rather, I can feel it pull at the shoulders), the shoulders a little wide, and I can barely button the top button. If I get a 16-33, will it be even larger in the shoulder? Should I get a fuller fit (slim instead of extra slim) so the shoulders don't pull, or is a little pull normal? I like the high armholes of the ESF fit though.
