Analysis of information sources in references of the Wikipedia article "Gyaru" in English language version.
The kogyaru [...] appearing in the early 1990s offers a more recent example of the way in which women who transgress gender ideals continue to be objects of critique. The kogyaru style, frequently marked by bleached hair, white makeup on artificially tanned skin, brash behavior, and a reputation for talking explicitly about sex and other taboo subjects, often, as Laura Miller notes, 'combines elements of calculated cuteness and studied ugliness.' It is a look that appears to be 'an affront to the male tastes of readers.' The white eye shadow and lipstick on the tanned or blackened skin of the ganguro or yamamba styles combine to create the look of a photographic negative. Sharon Kinsella found that readers' comments drew upon images of a primitive tribe or some kind of animal and suggested a 'sexual and racial delinquency' on the part of the girls.
