Ancient and weathered tartans

[Downunder Kilt]

I can wear the Weathered Mackenzie with a black or brown shirt, tweed tie and charcoal jacket. This would be ok for a formal event but probably not acceptable at a black tie event.

I don't know if there is a english language breakdown here, but formal is black/white tie. Or if during the day, formal would be morning suit equivalent.

For the OP, I would wear a weathered tartan to a formal event, in fact, I have, it was a MacLaren tartan kilt. The only difference to the Ferguson tartan is that our yellow stripe is your white stripe
