I agree that there are many tartans a person can wear and make a claim to or wear in honor of and those would be the first I would suggest a person get.

But if there is one you like and you have no connection - well if your scottish chances are either they are related to you some how,, OR your families used to steal cattle together at one time or another.

I am a traditionalist in that I think kilts should be tartan, but that is only my preference and I dont think it is wrong to wear a leather one, or a camoflague one, I would never wear one myself but I would never ever criticize a person for wearing one.

I have a MacPherson Dress and wear it from time to time becasue it is a sharp looking kilt. (My great great great great uncle Angus used to steal cattle with William MacPherson)
