In Blairgowrie there used to be a couple of older fellas that wore kilts regularly, but that was it. For us, and I think most Scots, a kilt is a substitute for a suit, but even then only on particular occasions. Growing up we used to wear kilts at times to International rugby matches, but that was more tongue in cheek than anything else. Some would paint their faces too in a big St. Andrews cross, but that wouldn't be recommended for everyday garb either.

There definitely is a "I don't want to be mistaken for a tourist" as well as a distinct cultural difference. You don't see many Scots running around in white trainers and sweat pants either, which is frequently the dress that preceded the tourist kilt. I think some of the push back comming from some in this forum when I point out traditionally, you don't dress to show up your host is part of that. Generally the British are much less comfortable loudly dressed and presenting themselves as the center of attention. Being the center of attention is not always a good thing, and wearing a kilt daily is certainly unconventional and likely to attract attention.

If your goal is to make daily kilt-wearing a norm, I wish you luck. I suspect however you will have to be happy being benign form of exhibitionist, which is absolutely fine. Just recognize it for what it is. Especially in Scotland.
