Wecome to the forum. There is nothing wrong with wearing whatever tartan that you wish to wear. Clan tartans are a relatively new development in kilt history. If you choose to clans tartan because you like the way it looks, no one is going to arrest you and charge you with the high crime of stealing another clan's tartan. I choose to wear the tartans that have connections to my family(Macneill and Gordon), but that is my personal choice< and Ron, aka Riverkilt would certainly not object to me wearing a Macdonald tartan if I chose to do so.There are also many tartans with no clan affiliation that you may wear if you do not feel right wearing another clan's tartan. See the link blow for more information. It is written by our own Matt Newsome of the Scottish Tartans Museum in Franklin NC. All anyone can ask is that you wear the tartan with respect, and try and learn a little about it.
