Dirks, yay or Nay!

[Fraser of Lovat]

So, this is my first post in the forum, I'd like to say to any who where up north for the Northern meeting Ball in Fort George, it was a hell of a night. I spotted a close cousin of mine sporting a handsome dirk while reeling. The ball itself is white tie as are most things I attend in a kilt ( except family funerals), so is it acceptable to sport a dirk and Sgian dubh in a white tie kilt outfit, or is it solely black tie, or is it only for pipers, or was my cousin being foolish and no one wears dirks now adays?!
