Nothing unusual though. The young always seem to adopt the fashion of the disenfranchised. My little sister went to a very exclusive private school in LA (with Cary Grant's daughter) and in the late seventies-early eighties, the fashion du jour was to dress up like homeless "bag" people. My parents were horrified. They had predicted that she would "turn her nose up at them" if she went to this hoity toity school and instead she was dressing like a bum. They could not figure it out.
