If I had a kilt for every day of the week, I'd probably wear it every day of the week.

A true Tartan kilt is a bit formal to me, but a UK, AK, NK, XK, they are just like another pair of shorts, or jeans. Granted, they are not work attire, but if I'm doing my own thing, then I'd rather be in a Casual Kilt.

To each his own really, it's up to the wearer, as it should be.
