I'll be attending a wedding in late April. I'll not be part of the wedding ceremony, just a guest, and of course I'll be wearing my kilt. I only own one kilt, a SWK Nightstalker, and haven't yet worn it formally. My plan is to wear it with a tux shirt, bow tie, belt, sporran, and either off white or grey hose w/ black flashes. And shoes of course. My question is; because I'll only be a guest, and not part of the ceremony, is wearing a tux shirt and a bow tie too formal?

I may buy a SWK heavy weigh Black Watch before the wedding, in which case I'll wear that kilt instead.
