Dame Vivienne Westwood, DBE, RDI (born Vivienne Isabel Swire on 8 April 1941) is an English fashion designer and businesswoman, largely responsible for bringing modern punk and new wave fashions into the mainstream.

Westwood came to public notice when she made clothes for Malcolm McLaren's boutique in the King's Road, which became famous as 'SEX'. It was their ability to synthesise clothing and music that shaped the 70s punk scene, dominated by McLaren's band, the Sex Pistols. She was deeply inspired by the shock-value of punk - "seeing if one could put a spoke in the system".

Westwood went on to open four shops in London, eventually expanding throughout the United Kingdom and the world, selling an increasingly varied range of merchandise, some of it linked to her many political causes such as CND, climate change and the civil rights group Liberty. She has been twice married, with two children.
