The "Cheap custom suits for Men" idea is described simply as "$100 custom suits for men.".

This reminds me of the Ali G episode where he presents his idea for the ice cream glove (http://www.youtube.com/watch?v=nkuOuxRD1Bc).

The Venn Diagram for $100 custom suits would have "all the people without much money" in one circle, and "all the people who want to be really well-dressed" in the other. The intersection represents a huge market, which means this idea is nothing short of brilliant.

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.)

I actually bought a $100 custom suit when I visited Shanghai. It was perhaps the best $100 I ever spent, it ended up looking really good.

I got a suit for €100 in Damascus a few weeks back. It looks awesome and is really, really comfortable. :-P
