Mary Quant was very influential ,in the 1960's, showing us teenagers that we did not need to dress like our mothers.
But there was a downside. She promoted the androgenous look of models like Twiggy - very skinny, flat chested , just like a young teenage boy. For those normal girls with breasts and hips this look was impossible to achieve.
And so began an epidemic of anorexia.
This is a medical article from 2001:-
"Eating disorders are a complex group of illnesses that often are seen in the adolescent female population. During the past three decades, the prevalence of eating disorders has increased dramatically; currently, the overall incidence is approximately 5 percent.1,2 Although eating disorders generally occur in adolescents, they are now seen much more often in children and adults, including the elderly.3 Initially, eating disorders were believed to affect only socioeconomically advantaged white women; however, this stereotype has not held true. These diseases affect persons of all social classes and both sexes.3 The increase in the prevalence and incidence of eating disorders is multifactorial.4 Increased awareness among patients and physicians is partly responsible for the increase, but the media, the fashion industry and changing societal norms are equally responsible.
This rise in the incidence of eating disorders can be best illustrated by tracing recent history. In the 1940s and 1950s, the movie star Marilyn Monroe, whose figure was curvaceous and somewhat Rubenesque, exemplified the ideal woman's figure. However, by 1967 a 92 lb British teenager, “Twiggy,” was the most famous fashion model and her “ultra thin” prepubescent body was perceived as the ideal figure for women. In the 1970s and 1980s, eating disorders finally received media attention with the death of singer Karen Carpenter, who died of cardiac complications of anorexia nervosa. This was the first time the media focused on the fact that eating disorders can have life-threatening consequences and are not simply a group of “benign” psychiatric illnesses. Since then, public awareness and understanding have continued to grow as more and more celebrities and athletes disclose their personal battle with these diseases. Unfortunately, icons such as the late Princess Diana of Wales
