Breaking the dress code? Like due to the rising "gang violence" in Sunnydale, the school bans the students from wearing "gang colors". Willow, in a fit of righteous indignation about freedom of expression, decides to deliberately violate the dress code. Could be funny if she got in trouble, or if her "gang colors" shirt had a cute kitten on the front, or if no one notices because Season One Willow is not anyone's idea of a gang member.
