I was looking for kilt pins online (why do hundreds of sites all sell the same 10 pins?) when I found this great page describing the parade dress of the Clan Gordon Highlanders Pipe Band in Locust Valley, Long Island, New York. Good descriptions, informative picture (which could easily illustrate a "do" if you are in a pipe band, a "don't" otherwise) and an explanation of the difference between pleating to the sett and pleating to the tartan, which I had not understood before.
