I am certainly not a source for the correct wearing of the kilt but, the Black Tie Guide has a page that speaks some on both Black Tie and White Tie with the kilt. Might be a start until more knowledgeable Members speak.

Also, there is a thread here that shows examples of Black and White Tie wear.
