Clan Chiefs and how they pleat their kilts

[M. A. C. Newsome]

From the looks of it, this kilt appears to have rather wide pleats, as well. I wonder what the yardage might be?

Actually, the more that I look at the photo, the more I'm thinking that this kilt may have typical narrow pleats, but be pleated to alternate lines, mening the yellow/white stripes only appear on every other pleat.
