If I may be suffered to divulge my opinion further, I'd like to elaborate on my position.

I do wear the kilt almost everyday at home and don't worry about crushing the pleats because no-one is going to see them. I find, however, that the kilt is impractical for being out and about. I often either ride my bike or the subway and find it to be a hassle concerning myself with modesty in such windy situations. I also usually have a lot of stuff in my pockets and don't feel like carrying a giant sporran. "So get a UK with lots of pockets and a modesty closure" you say?

This brings me to social considerations. The kilt draws attention and, while mostly positive, I don't feel like attracting peoples' looks and comments when I'm just going about my business. As Tobus remarked, sometimes the kilt is not so accepted or understood and I don't feel like explaining. When I'm working as a teaching assistant at the university where I'm a grad student, there is no dress code. I still don't want to wear the kilt because I'd prefer my easily distracted students to focus on what I'm saying and not what I'm wearing.

It is possible that if I were in a different time and place I'd think differently. Say if I were working in a blacksmith shop like Howard Clark, I'd want the ventilation. Or if I already stood out in crowd just for my ethnicity, like CDNSushi in Japan. Or if I were rich, had a kilt for everyday of the week, and a chauffeur to transport me around without giving everyone a free show!

As far as keeping the kilt special, I can see how reserving the tank for events and wearing a casual beater or modern kilt for everyday could work. Or dressing a tank up or down for different situations. My point here isn't as much about frequency (I already wear the kilt daily at home) but about communication. When I wear my kilt in public, I am signifying that it is an extra special occasion because it is not my usual attire.

This comes back to social issues because I understand that clothes express something to the people around us. As an example, people who don't care what others think might choose to express their rugged individuality by wearing clothes that raise the eyebrows of other people. That's great! I love to see people being different, especially if they are wearing a kilt. I am choosing to express the importance of certain occasions by wearing my kilt at those times and not at others.

This is all IMHO and I'm not trying to convince anyone to see it my way. Just documenting my musings on where the kilt fits in my wardrobe. It is interesting to see what other people are saying on the subject too... I'm a little surprised to see how many suggest that they would wear the kilt daily but that they don't. Is that just a financial consideration, which will be resolved as the kilt wardrobe grows? Or other issues?
