I agree with Jock Scot. Ask her family and see what they say. Even if they would prefer you don't use their tartan but you do want to wear a Kilt, there are very many universal tartans to use.


How about the

The Pride of Scotland,





or the Scottish National tartan???




Speaking as a Scotsman I can say that most sensible Scots are flattered and supportive when someone who was not born or brought up in Scotland wants to wear a Kilt.
So long as you are respectful I can't see any right-thinking person opposing the idea.

And, as a Donald, I can say that I certainly wouldn't mind you wearing any of the Macdonald Tartans.

Congratulations on the upcoming wedding and good luck!!!
