Look on the Clan Site-I think that should be good enough.

I think this comes back to the problem, that in many ways conventions are stronger than rules-yet people look for rules, and if they cannot find them-ignore those conventions.

Sadly I think this is a cultural problem, in that British ways are not of necessity appreciated by those who though speaking the same language, are not of necessity in communication.

To put it bluntly, after seeing it on the site as mentioned above, I would consider anyone outside the remit wearing that tartan as being an absolute rotter.
