Marc Jacobs began his fashion career as a stock boy aged 15. While still at Parsons School of Design, he sold his first collection of knitwear and was the youngest person to receive the CFDA's Perry Ellis New Fashion Talent award. Today his self-titled brand is a stalwart on the New York Fashion Week schedule, and its unforgettable collections and can't-miss shows often define the mood and key trends of the season.
