Emma Watson: From child star to fashion leader

It's 2001 and Emma is about to make an impression as Hermione Granger, Harry Potter's genius sidekick. She isn't making such a big impression on the fashion world yet - but she is only ten years old Photograph: Erik Pendzich /Rex Features

Two years later and it is becoming increasingly obvious that even at the tender age of 13, Emma isn't scared of a challenging outfit. She wore this full-length Egyptian print dress to the British Academy Children's Film And Television Awards Photograph: Steve Finn/Getty Images

Come 2007, there were rumours circulating that Emma was about to oust Keira Knightly as the face of Chanel's Coco Madamoiselle perfume. While the media speculated, Watson travelled the globe attending Harry Potter premieres. On most occasions she appeared wearing Chanel and was immaculately styled, adding fuel to the rumours.

After disappearing off the scene for the rest of 2007 (the rumours about Coco Madamoiselle turned out to be false), she ventured out again in February 2008, attending a VIP private viewing of Vanity Fair Portraits, sponsored by Burberry.
