I have no idea what that is, but I prefer the wider "A" shaped apron too...

However, I have been pondering a kilt made from overlapping strips of leather that are tacked, at the back of each strip, to canvis that is slightly pleated. The strips would be aranged like the pleats of a kilt, but I can't quite figure out how the apron would be done. It's all inspired by Roman skirt armor.

And really has nothing to do with those kilts, but since it's nighthawks thread...
