Tobus,

It could very well be a difference in the cloth, depending on who wove it. I own several four yard box pleated kilts, mostly in either Dalgleish or Lochcarron 16 oz cloth. I hardly ever have to repress the pleats to keep them looking neat.

I, for one, find the four yard box pleated kilt more comfortable to drive in than my 8 yard kilts, for the simple reason that I am sitting on less fabric!
