If you are fairly thin then it is possible to make a kilt from 4 yarns of material which might look alright in a fairly heavy cloth. It will not be very traditional unless you go for a box pleat

The more material the better, though, if you are aiming for a quality knife pleated garment. With extra cloth there is the posibility of deeper pleats at the edge of the apron, apron shaping, and deeper pleats all across the back. Even 5 yards might look a bit skimpy on some figures.

The amount of material required for an adequately pleated kilt is rather surprising - the first kilt I made I just could not believe that all that fabric was going to be necessary - and then I had to add in a bit to extend the under apron.

Buy yourself a pack of safety pins and tear up an old sheet into 2 ft wide strips, either across or along should not matter, and see if you can fold 4, 5 or whatever yards into a kilt for yourself. Pin top and bottom, iron to smooth the pleats then remove the pins from the bottom and wrap it around yourself.

A kilt maker can give it sharp creases, and shape the waist, but they can't magic in extra length.
