I'm happily commissioning my first bespoke blazer. I'm really looking forward to the process and completion. Oddly enough, my tailor here in Chile doesn't have a source for horn suit buttons. He has a nice selection of metal blazer buttons, but I'd prefer to use horn, to keep it less formal and slightly more versatile. I'm thinking brown or black. Anyone know of a good source? Shipping to Chile isn't a must as I travel to the states at least a few times a year, but buying online is. For those interested, it'll be a patch pocket (minus breast pocket) double vented blazer with a high-ish gorge and somewhat low button stance. I picked a nice all season fabric, which is either by dormeuil or scabal, can't remember.
