I agree with the low self-esteem assessment of your bosses wife. There's a woman at my office who constantly criticizes people to their face! She'll say things like, "Why are you wearing that?", or "What's with the hair?"..........you get the idea. She's single, a bit overweight, and obviously very unhappy with her life, despite the fact that she makes a butt load of money. Throwing insults at people deflects attention from oneself, a ploy that's common to people who are envious of someone else. The fact that you would wear a kilt proudly, especially one you've made yourself, probably just eats away at her because she must not have a creative bone in her body.

Wear your kilt and let losers like her keep making fools of themselves.
