In reading the thread "A friend asked my why I wear a kilt", a few folks mentioned that there are "inappropriate times" to wear a kilt.

I know that it would be frowned upon for me to wear a kilt to work. I'm an outside salesman and call on industrial facilities and coal mines. Outside of the fact that it would call unwanted attention, it would be considered dangerous to have a loose fitting garment that could get caught on moving equipment. However, I'm struggling to come up with other scenarios that would be inappropriate--outside of one's profession.

What situations do you find the kilt to be inappropriate?
