I think you need to pick and choose. I wore mine to my Canadian citizenship, what the hey, but I didn't wear sandals, did everything proper and nobody brought a camera.

I had another occasion last month to participate in a First Nation Day of Protest. I did not wear the kilt since I thought it would take away from their event. I didn't get a chance to discuss it with the organizers. As it turns out, I was invited to the front and my picture was in the paper. So I'm satisfied that I did the right thing. The Feather Bearer should be the focus, not the guy in the kilt behind him.
