My brother is like that (along with numerous other jerks in the family) but his girlfriend loves the kilt and is always making fun of him for being so idiotic/insecure about it. In fact she takes as much pleasure as I do in the shocked stares and insensitive whispers of my less than supportive family members.

Of course in his case it's just sibling rivalry. He was pro-kilt until I started wearing them. He used to wear one himself when we were kids.
