While waiting for my kilt to be made - complete with Prince Charlie and accessories for formal (technically semi-formal) wear, I'm pondering options as to what to wear it with on less formal occasions.

I'm particularly thinking of a family wedding that is going to be pretty laid back. If I were going with trousers I'd have worn a sport coat, shirt and possibly a tie, and dispensed with the tie at the first opportunity.

Assuming the weather is kind, I'm happy to dispense with the jacket all together, so was thinking a plain white cotton shirt. With the red and black predominant colours of the Cunningham tartan, I'm wondering if I can get away with another colour in the tie - black is definitely wrong, white is too formal, and red ... would have to match exactly at least. What are the rules around other colours with a tartan?

I'm definitely going to need a less formal sporran for this occasion as well.

OK, when the groom hears of the plan he might decide to join me (his now-deceased mother was a Scot)... :-)
