I find it kind of complimentary when I see a Menzies tartan on someone who has no affiliation to the clan. I see it as someone who just digs the tartan. We saw quite a bit of the Menzies Mourning tartan in shops all over when we were in Scotland. I was told that it was because of the lack of simple black and white tartans. It sure made it easy to find things though, compared to my wife the MacQuarrie.
