Two Telling comments? The Answer Perhaps?

[English Bloke]

In my experience, with some exceptions (Tartan army, Burns suppers, occasional weddings, street buskers, or folk generally regarded as eccentrics...) the kilt as a form of daily garb for men is as unpopular in Scotland as it is anywhere else. Most Scots who see a Kilt being worn in a non-special setting in Scotland, naturally assume foreigner / tourist. And to be honest, they'd not be far wrong. I'm chums with some Scots who have never, and will never wear a Kilt.

It's just the way it is. This is why it's important to encourage the Kilt both within as well as outwith Scotland or the whole industry around production of same will just fade away, or worse, be consumed by shoddy low quality imports. But that's an argument for another day perhaps.
