I don't think many western people realize that the 'normal' look in japan is pale skin and black hair, whereas over here it's normal for people to have blonde hair and tan, but not in Japan. That's why the Kogals and Ganguro started copying calefornia girls and western girls styles to be different. That's why Kuu is considered Gyaru because she also does the western style with fake tan and dyed hair. They even have pants in Japan to make girl's asses more round and 'western'.
If you go over to Japan and you have natural blonde hair, girls all ask to touch your hair and take pictures with you.
If people are still confused about the different types of Gyaru (such as ganguro, yamaba etc) then watch this part of an episode of Jonathan Ross's Japanorama that was shown on BBC:
Kuu is featured in part 3 of this episode, at 4:40:
I do kinda resent how he says they are simply Japanese counterparts of J-lo, Madonna, and Christina Aguilera, though. It really ticks me when people say that, when Kuu, namie and Ayu are original artists completely different, that quite frankly, I don't associate with J-lo, Madonna or Christina.
It dosen't really give examples of just normal Gyaru, which really is a more natural western look and high fashion, like EMODA. But it explains the more extreme styles.
Sorry for off-topic, I thought that would be a useful video to share.
I'm looking forward to the mini-live in December! Kuu never rests! D:
