Rationale: If women (European, Danish) can wear any tartan they like, I as a man can do the same. I know about the tartan – and clan – of course, should anybody ask, but most of my country fellow men hardly know about the existence of clans or tartans. They’ll just recognize differences in patterns and colours.
GG (and anyone else who might be interested):

This is certainly not a comprehensive list, but the introduction to "Tartan for Me!" and Electric Scotland's web site has a nice list of tartans for non-Scots:

They suggest that if there is a "Scottish connection" in a nation's history, then that is an appropriate tartan for a citizen of that nation to wear.

For example, the Sikhs might wear the Rattray tartan in honour of Rattray's Sikh Regiment, which still maintains contact with the Clan Rattray tartan. There probably is a Scot somewhere in Danish history (the Scots got around!), and that would not be inappropriate.

We're on the same course here -- bottom line, "imitation is the sincerest form of flattery", and all of my Scottish friends certainly think so! :mrgreen:

Shamalama, YOU have the ultimate authority on what a McCullough can wear -- traditionally, the Chief, the head of the family, makes that determination, officially (as in the case of the Duke of Argyll "excommunicating" Campbell of Argyll as a "non-official" Campbell tartan) or unofficially and by custom (my Chief, Sir Alistair Gordon Cumming, wears the Ancient Cumming Hunting tartan, so a lot of us in the Clan Cumming Society wear it), but in the end, it is YOUR decision.

Also, too, remember you have a choice of District Tartans as well -- if memory serves me correctly, the M(a)cCullou(c)ghs came from Galloway -- so you have at least two more tartans -- the Galloway and Galloway Red tartan -- too choose from! :mrgreen:
