Land's End and
LLBean seem to have a boxier cut.
Eddie Bauer might be another option. Have you ever tried them? They certainly have nice, simple, non-girly options. I agree that you might need to consider having things tailored if they just aren't fitting off the rack. It is nice, though, if you can find a brand (even just one) that fits when you bring it home. Good luck and hope it was okay to visit this part of the board.
