This character is see in or described as being part of Gyaru fashion.
Gyaru fashion is a type of Japanese street fashion that originated in the 1970s. In English speaking countries Gyaru is commonly mistaken for ganguro, but that is actually a subculture of gyaru. Gyaru is a girly-glam style, breaking away from traditional standards of beauty by dwelling on the man-made (wigs, fake eyelashes, fake nails, etc).
Gyaru fashion is typically characterized by having heavily bleached or dyed hair (mostly shades from dark brown to blonde), excessively decorated nails, and dramatic makeup.
The makeup typically consists of dark eyeliner and fake eyelashes used in ways intended to make the eyes appear larger. Clothing pieces for gyaru fashion differ depending on which gyaru style the individual chooses.
