My FI and I are paying for our BM/GM/GWs outfits, and the GM and GW are wearing my FI's tartan, and my BMs are wearing my tartan. I would like everybody that is going to be in our pictures are either wearing my FI's tartan or my tartan. However, my problem is that my parents are divorced, and have different surnames and therefore different tartans (I have my mother's). I want to ask my Dad to wear my tartan, as he will obviously be in the wedding photos, so that he doesn't look completely out of place since not only are the tartans no the same pattern, they are not the same colour, but I'm not sure how to go about this. It means a lot to me that he still looks part of MY family, and not just some random stranger, but I still don't think it will go down well.
What would be the best way, do you think, of asking my dad to essentially wear something that basically brands him as my mother's family when, I assume, his brothers (who are not in the wedding photos) will be wearing his own tartan?
