The only episode around here that I know of:

A buddy of mine several years ago (when he was in High School) wore a fashion tartan to school. I don't guess it even had a name... was one of those types you find in mall stores. I've seen it, and it's constructed with three straps and the whole bit (surprised me.) Anyhow, he was told he could not wear it. When a protest (by his wealthy Irish Parents) was made, the school made a compromise... he could only wear a kilt if it was his family tartan. HA! I sort of saw it as a battle half won...
