During the two years I lived there (85-87), it was rare to see a person going about their daily business in a kilt (although the gentleman who ran the local shoe repair shop did.) As mentioned elsewhere wearing a kilt was generally treated the same way we in the U.S treat wearing a tuxedo. (On the other hand students at St. Andrews University did wear really cool red robes on and off campus, sought of like a Harry Potter movie.)

Best regards,
