I thought I would make this thread because a lot of people don't know how to distinguish between the different CURRENT Gyaru trends, or actually know any of them apart from Ganguro.
ギャル系・ GYARU-KEI
General style, which doesn't require a tan, although most gals have one.
Fashions can be worn by both Ganguro (tanned Gals) or Ganjiro (untanned Gals).
Has many sub-categories.
ギャル男・ GYARU-OH
Male counterpart of Gyaru.
Hair is often in a mullet style, ranging from light brown to silver to pink!
Usual clothes are clubwear, sweats with tank tops or a stylish jeans + tank top + open shirt combo. They don't wear makeup but are usually well tanned, although a tan isn't a requirement.
マンバ)・ MANBA
The updated version of Yamamba. Manba has evolved since 2004, when it featured a lot of hawaiian prints, leis, face stickers and pastel-coloured hair. The style now has much thicker white makeup, brighter and more varied coloured eyeshadow, light to extreme panda makeup, coloured eyelashes and diamantes around the eyes. Clothing ranges from neon clubwear to sweat suits, but no longer includes the hawaiian accessories or hude amounts of stickers under the eyes. Hair tends to be bright, flourescent colours or blonde and is cut in a mullet style or braided.
姫ギャル・ HIMEGYARU
Meaning Princess GAL it is a style characterized by pink make-up and long eyelashes as well as either tan or very light skin. Huge hair in a bouffant/beehive is practically the uniform. Lots of fur and rich materials as well as lace and velvet are common. High heels are always a must, as well as a good structured handbag preferably white, black, or pink. Animal prints as well as rhinestones, roses, orchids, and other flowers
There are many many more styles that I haven't mentioned such as banba, sentaa etc. I thought it was best to keep with these to start with and if people want to know more I am happy to post again.
