first in London and Paris. Among her regular assignments at that time were jobs for the UK edition of Vogue, Vanity Fair, Elle in France, and Honey, as well as fashion spreads in newspapers such as The Daily Telegraph and The Times. She was photographed by David Bailey, Terence Donovan and Brian Duffy, among others, and appeared on the cover of British Vogue. Other popular models of the day, such as Twiggy, based their modeling appearance on Boyd. In the description of journalist Tom Hibbert, Boyd and Jean Shrimpton became "international celebrities" as the embodiment of the "British female 'look' – mini-skirt, long, straight hair and wide-eyed loveliness".

UK underground writer Barry Miles later described her as "by far the most glamorous" of all the Beatles' wives and girlfriends, while author Shawn Levy writes that, even more so than Jane Asher, the London-born stage actress who was Paul McCartney's girlfriend for much of the 1960s, Boyd epitomised what "sixties stardom was meant to confer upon its chosen". Writing in 1966, British fashion designer Mary Quant commented that it had become a requisite for contemporary women to strive "to look like Pattie Boyd rather than Marlene Dietrich", adding: "Their aim is to look childishly young, naïvely unsophisticated, and it takes more sophistication to work out that look than those early would-be
