1. Do you wear kilts full time or have that as a goal?
Full-time outside of work, with a couple of exceptions.

2. Why?
Why not?
Seriously, they're more comfortable than pants (and better looking than sweat pants), warmer in winter, are cooler than shorts in summer, allow greater range of motion in comfort ... but I'm preaching to the choir, aren't I?
Secondarily, where I work dictates my appearance at work - uniform, haircut, facial hair, visible body piercings, tattoos, or jewelry, my behavior at work, and to an extent my behavior and actions outside of work. My kilts are a way of saying "This is me - my culture, my heritage, my family, my individuality, and these things cannot be taken away from me." And if they say or do anythin, they break their own rules about cultural acceptance and tolerance - they will be in trouble with themselves.

3. Do you believe promotion of full time kilt wearing is important?
No.

4. Why?
Those who are genuinely interested will continue coming to us, the kiltwearers, and they too will start wearing kilts. Promotion runs the risk of creating a fad, instead of encouraging the wearing of a traditional garment.

5. Do you believe kilts will ever be considered a mainstream fashion choice for men?
Mainstream - no. A large population along the periphery - yes. Accepted alternative for daily wear - hopefully.
And if the fashion sheep won't accept the kilt - shear 'em and make kilts out of it!
