Both Phil and Matt (and others) have raised some cogent points regarding how hard it is to define traditional and where the line is drawn between traditional and historic (and in some cases, eccentric!) Highland attire.

Matt's observations on the box pleat kilt perfectly define the conundrum. If worn with a Crimean War military uniform the 4-yard box pleat kilt is historical; worn with a Prince Charlie coatee it most definitely becomes traditional. I'm actually a fan of the box pleat kilt because I consider it "traditional". Matt would most likely agree, and there are probably some who wouldn't.

Phil has hit the nail squarely on the head when he said that this form should be a place "of gentle advice, rather than opinions set in stone." I'm sure that's something we can all agree on.
