As a guy who runs a kilt shop and hears the question originally posed in this thread on a daily basis........

There are currently well over 15,000 Registered Tartans. More are designed and registered each day.

The original question of this thread seems to assume that there are only Clan Tartans to choose from. A sort of "Someone's Clan Tartan or nothing" way of thinking.

There are many many Tartans that have no connection whatsoever to any Scottish Clan, Family or name.

If anyone questions what Tartan they can or should wear I could simply hand them a set of Tartan Swatch Books. I could promise to tell them if they pick one associated with a Clan. The chances are pretty good that I would not have to tell them "No, that one is a Clan Tartan" too often.

I personally own 7 Tartan kilts and not one of them is a Clan Tartan. To my way of thinking there are simply so many Tartans choose from that I don't need to worry about offending someone or wearing someones Tartan.

If any member of this forum wishes to wear Tartan they need look no further than our own X Marks Tartan. You are fully authorized to wear it and I have it on pretty good authority that you have the forum owners' permission and blessing to do so.

Don't like Blue? OK, there are only about 13,000 other non-Clan Tartans to choose from.
