Oh dear-back to rules.

You'll no find them in a book-or set out by this or that authority.

Sorry here I have to be blunt, rude even: there conventions, and you either know the conventions, or you do not.

It is as simple as that.

Where can you find out about them?

Well no one is going to say-or write a book: the best suggestion is to observe people wearing highland dress-possibly reports of games in the highlands will be your best source. See what is being worn and how.

A tip being to ignore the dancers-bands and visitors: look at the judges and the like.

Sorry.
