This is really good advice, especially if you are short of funds, unless of course you want to go ahead and buy the whole outfit. Definitely in vest in the hand tailored kilt, as you will get the most use from that. Unless you plan on attending many formal events, you would probably be better off renting a Prince Charlie jacket, waistcoat, and formal sporran, but again, that's up to you.

As far as underwear, you'll get arguments for and against here on the boards. In my mind, that's a personal choice that only you can make.
