With the proliferation of online MTM shops (ModernTailor, Cottonwork, MyTailor, et al.), I imagine there must be a place that offers alterations services by mail. I'm looking to get a fairly big batch of shirts altered -- mostly tapering/darting on the sides, and possibly some slimming of the sleeves. Not overly complex alterations, and probably nothing a halfway decent alterations tailor can't handle. The trouble is that my schedule is crazy, I'm traveling pretty much nonstop, and I don't have the time to take these into a B&M tailor. (I'll take my better shirts to a real tailor, but these are shirts I don't care quite as much about; I just need them done serviceably and at scale). Anyone have a good rec?
