I've gotten some of my more unusual looks from Chinese and Japanese nationals, who honestly in many cases have never heard of or seen the kilt before. Most are very respectful, very curious, and in the case of the Japanese often overly polite (to the point of curbing their curiosity a bit too much).

Given that the kilt might be completely alien to many from the far east, I try to keep that in mind when dealing with people from that region of the world.
