Budding fashionista Emma Watson makes a surprising red carpet choice

Emma Watson stepped out at a special screening of her new film 'The Perks of Being a Wallflower' in a fashion forward Dior design in London last night.

A sweetheart neckline and a tulip skirt sounds conventional enough, but the quirky fashionista wore the dress over tailored black trousers.

A skirt over pants has fashion faux pas written all over it but surprisingly the ensemble worked for the young actress.

Watson completed the look with a glam curled 'do and a gorgeous silver key necklace.

Despite being a silver screen veteran at just 22, and widely admired for her sense of style, Watson has confessed that she still struggles with watching herself on screen.

Her new film, Watson told BBC radio host Nick Grimshaw in an interview this week, really pushed her out of her comfort zone.

"It’s really funny because when I watch the film back, there are a few things I can’t watch," she said. "I can’t watch the Rocky Horror dancing scene, and I can’t watch the kissing scenes."

Watson said she told director Stephen Chbosky that the new role was a big change to playing Hermione Granger.

"You are expecting me to dance and putting me in corsets, and it's difficult," she told him.
