Traditional Highland Wedding Attire?

[Chip]

Doing my part to try to get back on track, I did not wear a kilt to either of my weddings, though the best man did at my second (I wore a morning coat). Were the occasion to arise or if I had it to do over again, I'd wear a charcoal tweed with waistcoat along with my kilt.

Resurrecting the plaid discussion a bit...

C.R. MacKinnon's Scottish Tartans and Highland Dress, though somewhat dated (1960), states in the section on formal evening dress (e.g., white tie):

"A [full or belted] plaid is optional, except that if this dress is being worn by a bridegroom it is then desirable that a plaid should be worn. Bridegrooms, incidentally, as with Lowland dress, have the choice of morning dress, lounge suit, or evening dress, but in Highland styles."

He does not discuss the fly plaid at all, so I assume his work predates them; though based on his take on most "modern" additions to Highland attire, I think he would probably have disapproved. He also does not list plaids of any sort in his "informal evening dress" (black tie), which I think is both interesting and appropriate!
