First, apologies if this topic should be in a different forum. If so, please let me know to where it should be moved.

Second, what is the rabble's understanding of the wearing of a clan's tartan? Specifically, aren't there rules that state only the members of that clan may wear that tartan?

I know about universal tartans and how anybody can wear them. Given that, I thought that unless a tartan was/is considered universal, the wearer must have a connection to that clan. Otherwise, it's not proper. Right?
