When I purchased some Robert Noble tartan from an ebay seller, I had it shipped to a friend in Plymouth who was coming to visit me some time later, as he so willingly cooperated in bringing it, saving me some post money. His comment was "Kilt, kilt, what are you going to do with a kilt ? Those are sold to tourists on the Royal Mile in Edinburgh, and you'll never see one otherwise, except at weddings, rugby, and football."

My observation is that likely many Americans and Canadians wear a kilt more frequently than most Scots do. Strikes me as curious, but I am sure the reasons are numerous and complex.
