Having been off the forum for all too long yet again, I chose this thread to read all the way through. Sure enough, the same debates continue, which is a comfort of sorts.

I am of course a non-Scot who happily wears a kilt for all manner of occasions, formal and informal, but wears the Maple Leaf (Canadian national) tartan most specifically for tramping about with students in WWI cemeteries and former battlefields in honour of our kilted regiments; I like to think of my Highland Granite box-pleat (shades of grey and a little old-fashioned) and new Black Isle tank (black on black, very traditional) as nodding - differently - to my Mennonite heritage, while the Highland Cathedral (named for a pipe song written by Germans) signals the whole cultural mix/cross-over fairly nicely. (We can leave aside for now the academic inclinations that brought me the Macbeth military box-pleat ... and indeed the initial kilt-wearing.)

But Canadian national costume? I think I'd be stuck wearing a toque and snowshoes and very little else, which would not serve anyone very well at a banquet.
