First post and first kilt

[vorpallemur]

One last question. I understand a box pleat and a knife edge pleat, but can someone describe a reverse Kingusse pleat?

It's what Utilikilts, and a number of other contemporary kilts are. A traditional kilt has knife pleats, all opening towards the right hip. A reverse Kingussie pleated kilt has knife pleats going towards the back; they meet in the center back, in a box pleat. It's got some advantages over traditional pleating; it's easier to sit in, for one.
