A type of kogal taken to the extreme: school uniforms characterized by tiedopen shirts (exposing not just the midriff, but the chest as well, showing off the bra/bikini underneath), and a short-enough skirt that panties may be revealed, emphasizing the wearer's body. Paired with these are accessories and make-up.
Referred to as "American School" (or Amesuku) style in Japanese, based on what the Japanese think American girls would wear in high school, bolstered by gravure and AVs featuring the attire (potentially inspired by the outfit Britney Spears wore in "...Baby One More Time").
