I know she is perceived as a super bitch but she also has the job that most fashionistas dream of. She has been editor-in-chief of American Vogue for nearly 30 years. She is known for her trademark sunglasses and bob that she has has since she was 14 years old.
After joining the magazine Wintour began to stir things up with new ideas. She suggested that covers feature the models body as well rather than the tight head shots that were used before. She also mixed less expensive clothes with high-end fashion. The magazine cover on the left was Wintour's first. The model is wearing $50 jeans and a $10,000 top from Christian Larcoix; it was the first Vogue cover to feature jeans. Wintour's decisions received mixed reactions from big players in the industry but Wintour wanted to show the way real women put together clothes (however I don't know any 'real' women that own $10,000 t-shirts...).
Anna Winotur's role in the magazine has changed the shape of the fashion industry we know today and has made her the most powerful person in fashion; now who wouldn't want to be her?
