Of course there are many work situations which prohibit kilt wearing and that's far from unique to Edinburgh or even to Scotland.

But like all towns and cities there are many people not at work at any given time and they are in any case free to decide what they wish to wear in their leisure hours. The trends and fashions they then adopt cannot be put down to work however but factors such as peer pressure then come into play, especially amongst the young. One can see the same "uniform" all over.

Yes indeed kilt wearing was viewed by Lowlanders as a Highland thing and the prohibition of the kilt touched them little if at all. That didn't begin to change until the visit of George IV to Edinburgh when he set the fashion by wearing a kilt (albeit with flesh coloured stockings) and later by Queen Victoria's espousal of things tartan. But it still wasn't seen as everyday attire and still isn't whether it's in Inverness or Dumfries (with honourable exceptions of course!)

So changing the culture a little on that point is I agree, a challenge. Hopefully where Edinburgh leads the rest of Scotland might follow.
