May I chime in?
I was noticing that the "kilts" in question at pullteeth, with bulky pants underneath, cause the "kilt" to twist in a funny way. That is, the smooth swish was lost. So what is the point in wearing this?

In these fashion shows, the garment is often made on the fly so to speak and pinned together not sewn at all and hence garments often look sloppy.But the under trousers were pulling on the "kilt" contraption it would appear.

But I agree its either trews or kilts not both.

When we were young we had short kilted skirts with shorts attached and these were called "skorts". This garment should be called "the skirted trouser".

I agree that this fashion will never take off and some may even find it actually a mockery of the kilt rather than an homage.
