An in depth (as far as you can get) look into Tokyo teen fashion and it's subculture groups. It focuses on fashion groups dating back to the 50's and provides detailed descriptions of the trends as well as diagrams, must-haves, and ideal boyfriends. At times it is rather facetious and points out rules for fitting into the Mamba subculture (#6 You must not have a smelly pussy). It managed to entertain me.
