My very first kilt ever was a great kilt because it took little effort and it was extremely cheap. I just went down to the local fabric store and bought 4 1/2 yards of good looking plaid. It looked a lot like the blackwatch tartan. Then all you'd need to do is pleat it,tie on a belt, and pin it at the shoulder. He wouldn't have to spend more than 25 bucks.

Obviously the more money he is willing to spend the better looking he can be, but if he's just looking to have a kilt and doesn't want to spend hardly any money, this is a pretty easy way to go.

You can always look online to find out how to pleat, and belt etc.
