I had that idea 3 years ago and even sourced the tailors in Vietnam :-) I want to Saigon with a backpack full of GQ, Esquire, and tons of catalogs. All that came out of it was some tiny tailors started making fashion-house suits in some Saigon slum and nothing was exported due to the messy business that is Vietnam shipping industry (they work best when you stay in the country and show up at the port. Vietnam Post is unreliable for frequent small shipments, for made to order garments. If you're gonna do business with locals make sure they have a $ stake in the venture, and foreigners there are slacker-type teachers, isolated in their own expat-communities and are not very business minded.)
