What is Traditional Highland Dress?

[Lyle1]

Dress as the ordinary Highland Scot would dress.

Except, hasn't it been mentioned in several discussions on this forum that the "ordinary highland scot" rarely wears a kilt?

I think that you are coming very close to taking traditional highland dress into the realm of historical reenactment, which is fine for those who want to do that. The thing is, though, that you need to recognize that the rules only apply to those who want to assume the highland dress role. The rest of us can wear whatever we feel is appropriate. I am not saying that wearing what you feel is "correct" traditional attire is wrong, but it is wrong to criticize and/or ridicule kilted folk who don't dress by your rules (and you do of course know that there are not really rules on how to dress).
