LW3: Okay, on one hand, traditional clothing from another culture is not a "costume", and I feel that to wear it as such could come off as insulting and would be a bad idea (that was my basic response to the original letter). On the other hand, I disagree with Amy that one should not wear clothing of a culture not their own;  I would have no issue with a non-Indian woman wearing a sari, as if Indians somehow own the style. If we apply such "appropriation" rubbish to other areas-- say, food-- I wouldn't be able to eat a taco because I'm not Mexican.
