A suit is not a travesty for a Burns Supper, in fact I've been to a few where most people, most of them born in Scotland wore suits.
I said that mostly tongue-in-cheek. Being a kilt related board, I figured we would all understand the extreme dislike of wearing pants to a celebration of a Scottish cultural icon.

Personally, I would think it IS a travesty if a person wants to wear a kilt to Burns night but feels some reason that it wouldn't be right.
