As for my kilt, It is what it is. A WPG Cameron box pleated kilt. That is what it will remain.
You should talk to Matt N. about one of his box-pleats, as its buckle & strap on the left hip is based on a 79th kilt at Gettysburg. In fact, I believe Matt has made a box-pleat in the Cameron of Erracht tartan for a reenactor.
