I don't think you are limited to just three layers of fabric for box pleats - at least, I hope not - there is one pinned together in my stack of things to finish where the waist line has five layers of fabric.

It just seemed to be a logical development of the concept, to put more fabric into the kilt by making each inner fold longer.

It can also be made into a mirror imaged kilt, by having the backward or forward facing part closer to the outside than the other one.

Pressing it is going to be interesting.
