I've worn kilts to my company holiday galas for 3 years in a row now, after wearing suits for the 2 years before that.

It's true that EVERYONE notices you (this year more than in the past, as my company was aquired by a major bank so there was a group from Toronto in town), and i'm ALWAYS the only one in tartan. As a result, every year, the CEO insists on introducing me to his wife, and having a picture taken...

Nothing but good things!
