She married Derek Westwood in 1962 (divorced 1965). In 1965 Westwood met and moved in with McLaren, future manager of the punk band the Sex Pistols. Eventually, they operated Let It Rock, a stall selling secondhand 1950s vintage clothing with McLaren's rock-and-roll record collection on The King's Road in 1970.
In 1976 they dressed the Sex Pistols with McLaren. Westwood's designs of the band help it carve out its identity.
