Yes, I do wear the kilt for casual wear, but not on a daily basis.
I do not, and can not wear the kilt for work. As a surveyor and construction inspector it just wouldn't be practical.
Yes, I do wear the kilt for "social occasions" (i.e, out drinking, to parties, etc). I wear it out to our local pub on occasion, or out to supper, or when my wife and I are out on the town. I've work the kilt hiking, and at Walt Disney World as well.
I have worn the kilt to events such as balls or galas, but never have worn the kilt to a wedding or a funeral.
Outside of highland games I'm the only one kilted 95% of the time. There are a couple of guys with kilts in town, but they rarely wear them, and a couple of guys I know who have Utili-Kilt style kilts and while one wears his pretty regularly, the other doesn't.
