Katelyn - I may have missed it but you don't mention if you are a member of a clan?

If you are not, then I suggest your husband could honor his clan by placing a sash of his tartan on YOU after you leave the ceremony or when you get to the reception. You could make a bit of a show of it. This is a great way for him to "welcome" you into his clan and would, perhaps, eliminate the need for him to wear any tartan at all.

Just a thought. Congratulations and best wishes.
