At the moment Ganguro is a little dated, it moves in and out of fashion all the time. Gyaru ( a more modest form of Ganguro ) tends to stay in fashion more, and it is basically tanned girls with shorter skirts, without all the heavy makeup and the hair doesn't have to be dyed.
It's funny how there's a thread that makes the argument that all asian girls want to be white-- when in reality it works both ways (Just like with non-asian girls).
This fashion died years ago. Except for those who never grew-up. Haven't seen a serious sporter of this fashion for moons unless at a festival club or flashback scene .
