I don't know Steve, I seem to recall some pictures of you that are distinctly THCD in my view. Whilst I agree the definition of a traditional kilt that you describe above leaves little to discuss. It is what goes with it that is where I think people have trouble with and that is a moving and elusive target. For example in certain circumstances, bare chested and barefoot with a traditional kilt is perfectly THCD on the beach, on the rare occasion the sun comes out in Scotland. This sort of variation from the tweed clad, tattersall shirted, Regimental tied, cromach wielding , brogue wearing "Kyle/Jock type" picture, is I think, difficult to grasp for those not understanding the wide range and subtleties of THCD.

Now I have admittedly little to no(OK none) experience of the other styles of kilts, so I can only give the impressions that I have gathered here and some tartan kilts of more modern construction and yes, materials too, being worn with, for example, a pullover and open necked shirt, with reasonable shoes, hose pulled up and reasonable sporran certainly gives the impression of THCD. So before getting to the MUG definitions there is a huge grey area that we all will have trouble defining when considering what is worn above and below the kilt. In other words it is the overall look that, in my view, defines THCD or not.
