Tartan-wearing conventions among Scots

[Jock Scot]

What about folks that don't have a "clan or family tartan" associated with their surname?

Yes I see what you are getting at, in truth no one asks! I suppose we assume some sort of clan connection. Another reason for only wearing one tartan, as we usually do.

I can't say that I have really noticed, but district tartans are not really worn by individuals, I think that on the whole we would probably assume they were for pipe bands, if we give it any thought at all.
