I'm looking to get a MTM sportcoat soon, and the clothing store I go to uses the Southwick MTM program. I've done a bit of reading, and all I can seem to find is the fact that they are half-canvassed (and also that John Kerry seems to like them, although I'm not looking for style advice from him). Does anybody have any experience with them? I'm also curious as to what the fabrics are like, and how much customization they allow for. Can I alter the lapel width? Can I opt for functional cuff buttons? Thanks in advance for any information.
