No one wears tartan for no reason, unless it is a flannel shirt. To most, "I like the colors" is a laughable and idiotic answer. The clan would be offended at that.
I usually don't put in my 2 cents, but after reading through this post and coming to this statement, I felt I had to. Most people who are not of Scottish origins choose the tartan they wear by color first and then the symbolism, honour or history behind it. How many people go to a website and look at the tartan colors and then the clan assosiated with it. For instance I like the Buchanan Tartan colors and decide to purchase a kilt. I have no Scottish ancestory, that I know of, but I lived in Pennsylvania at one time and our 15th President, James Buchanan was from PA. I also dated a girl who's mother was a Buchanan. But you know, I live in New Mexico now and I no longer date that girl. BUT I LIKE THE BUCHANAN TARTAN! So I'm buying it because I like the colors. Of course, I research the tartan after I've decided on the tartan, learn about the clan and it's history, but in the end I like the colors and that's why I decided on that tartan.

How many people would wear an ugly tartan, not that there is any, and be confident and proud? Who's to say what anyone can or can't wear a tartan JUST because they like the colors? To alot of us non-Scots, it's about the freedom to be able to wear what we want to wear.
