As someone who wears both traditional and non-traditional kilts I'd be concerned by this. Some of the casual garments which I wear are not what the kilt snob would regard as a kilt, yet they are perceived and accepted by the public as kilts. I think the kilt needs to be allowed to evolve as a fashion garment. By all means have standards for traditional dress wear kilts for formal occasions, but I do think there has to be freedom regarding casual wear kilts.
