One interesting story of clothing adaption taken from a particular culture is the current TOMS shoe craze. I'm told the founder of the company was a contestant on the amazing race. While in Argentina, he admired the interesting look of the Gaucho shoe called alpargatas. Later after returning to the States, he started a company called TOMS that manufactures these shoes taken from Argentina. I now see the alpargata knock-offs all over the New York Area.
Maybe I should start a Vietnamese coolie hat company?
