I wear my kilts around campus often enough, and no one has said anything negative about it. Most of the guys are like "hey, badass" or "it takes balls to wear a kilt" and such to that effect. Most of my lady associates usually just tell me that I look nice, and for the most part, my professors don't bother much either way... save for a time in SOCS185 when we were talking about race and ethnicity...in which case my professor looked at me and asked "Scottish American?". My reply "Anglo-Scottish"... that was a fun class, with a fair amount of humour (my professor for that one was very knowledgable in the realm of sociology, and quite good natured).

I have rarely gotten negative comments out and about. The one time I did, I confronted the kid on it, and he nearly crapped his pants. Just the whole respect other cultures and what not ordeal... I mean... everyone spouts the whole "respect others' cultures" rhetoric, but only care if it is their particular culture that isn't being respected. So it is a great way to pin someone and make them feel like a jackass for not keeping the mouth shut.

9 times out of 10, I don't care if people are dumbfounded by the kilt. The 1 out of 10 usually ends up in a brief conversation with someone because it is relatively out of the ordinary.
