so run the tie a bit long and then tuck into the top of the kilt. i like this advice, thanks!
wearing a waistcoat with tie this ensures the tie is not peeking out from the waistcoat, which i agree is unsightly.

question: white shirt + black hose = black tie?
I wouldn't wear a tartan tie but i like the idea of a red tie that matches the red in my tartan.
Would this be acceptable?
