Costume makers are pretty amazing tailors and seamstresses, from my experience. So if one that you are friends with wants to tackle the job of knocking out a kilt, BUY BARBS BOOK and give it to them.

After reviewing it, they may change their mind, I might add.

Making an X-Kilt or what I call "throwing kilts"...meaning simple fabric with a mess of folds in the back, two overlapping aprons in the front and a waistband is dumb-dumb easy for a costumer. Making a real, no-holds barred traditional KILT with all the features is NOT so easy. For a costumer it will not be particularly difficult, but it WILL be time-consuming.
