if you like it wear it.

as for states....i also, have no ties to any since i've moved around so much. if you are thinking that route, doesn't the u.s. have it's own tartan?

really if you find a kilt you like, wear it. no one is going to care if you are wearing a macdonald, but have no family affiliation with them.....well some over the top people at the highland games might, but so what? i have only a couple times been asked what my kilt is. and after answering that question, that was the end of that.
