I may skew your stats a bit, but the only kilt I own is the expensive wool variety. I bought is when I was younger, but to me it was something to be worn only at certain occasions, and most of those were formal. I have a good friend who was for a time very much into his modern style kilts but no longer has any that fit due to weight loss. I had not really got into the idea of Kilted culture such as is discussed here and elsewhere, until recently. Now I look for excuses to wear my Kilt, although I doubt that I will ever own a modern one.
