When I go north of the border, even if it's only for a day's mooch about the capital, I ALWAYS wear my kilt. The trick to not stand out too much is to dress down, though, at the same time.

I generally wear my kilt with walking boots and a plain shirt or T-shirt in the summer and with a jumper (light lambswool or heavy cableknit depending on whether it's dipped below zero).

Cheers

Bruce
