A poll of celebs that ladies most like to copy was topped by the Duchess of Cambridge.
In the survey conducted by online make-up store feelunique.com, a third of British girls said that Kate is the person, who most influences them when they buy beauty products, the Daily Star reported.
The figures are the latest example of the "Kate Effect" that has transformed everything from sales of jeans to jewellery since she married Prince William in 2011.
The Princess won twice as many votes in the survey as the runner-up, supermodel Kate Moss, 39.
The third place was bagged by former Spice Girl Victoria Beckham, 39.
It was found that 11 percent of the respondents named English fashion model Cara Delevingne as their inspiration for buying beauty products.
