Vivienne Westwood was instrumental in creating the punk rock movement in England through her fashion designs and shop that promoted rebellion and nonconformity. While she broke from punk rock when it became mainstream, she reinvented herself as a highly innovative fashion designer with an avant-garde approach. Westwood's lack of formal training allowed her to be more creative and cut through conventional design rules. Her understanding of history and manipulation of fabrics created sculptural silhouettes that emphasized femininity in unconventional ways.
