I'm an elementary school teacher and wear my kilt to work on occasion. The kilt is a big hit with my fellow teachers and the principal. The kids were at first a bit suprised but that wore off after a few wearings.
The only bad experience I have had at work was with a parent. This fellow said "Nice skirt". I glared at him and corrected his mistake in proper elem. teacher style. I wanted to add &^#$head but there was a few students wondering around at the time. He didn't say anything else.
