I think I've mentioned this before, but I've had an experience where I was in the hotel lobby on my honeymoon and a little girl came up to me and asked me why I was wearing a skirt. I tried to explain that is was a kilt, Scottish, and men wore them. She just said "well it looks like a skirt to me" and went back to her family. This was early in my kilt-wearing life so I couldn't think of much else to say, but other than maybe making a reference to bagpipers I'm not sure how I could have explained futher in a manner to educate or trigger a memory of something she had seen before.
