1) Daily, for the last three years, except for 4 months while backpacking recently. (But I have backpacked over 5,000 miles in a kilt.)
2) I work in a restaurant in a kilt, and I've worked in a professional office in a kilt.
3) My last serious girlfriend honestly didn't like it that much, but understood that it's what I wear, so she was fine with it. Any girl who meets me meets me in a kilt. That's just how it's going to be. If they want to go out with me, they're going to be with me in the kilt.
4) I tell them it's comfortable, and that the chicks dig it. The guys wonder what I'm talking about, and the girls nod.
5) Who knows? I see them once in a while around town, but I don't think "popular" is the right word.
6) I'd love to get fewer people gawking over it, but then again it's kind of nice when the girls gawk.

Andrew.
