Ten months later, she became editor of US Vogue. Under Mirabella, it had become more focused on lifestyles as a whole and less on fashion. Industry insiders worried that it was losing ground to the recently introduced American edition of Elle. After making sweeping changes in staff, she changed the style of the cover pictures. Mirabella had preferred tight head shots of well-known models in studios; Wintour's covers showed more of the body and were taken outside, like those Diana Vreeland had done years earlier. She used less well-known models, and mixed inexpensive clothes with high fashion: the first issue she was in charge of, November 1988, featured a Peter Lindbergh photograph of 19-year-old Michaela Bercu in a $50 pair of faded jeans and a bejeweled jacket by Christian Lacroix worth $10,000. It was the first time a Vogue cover model had worn jeans (Bercu was originally supposed to have worn the skirt that coordinated with the jacket, but she had gained some weight and it didn't fit).
