www.scottishkilts.net is selling Stewart Hunting in Polyviscoe for $75 US. It is a bargain in that price. From what I heard from other people here, they will deliver you kilt within a couple of weeks.

It depends on how many Blacktie event you go to in a year, it may be cheaper to rent the jacket from your local Scottish store.

If you don't mind buying a second hand jacket, ebay is good way to go. I bought a mint condition argyl jacket for under $100us.
