Twilight star and emerging fashion favourite, Kristen Stewart, has just been announced as the face of the new fragrance from fashion giant Balenciaga.

Stewart, (22) who earlier this year was announced as the world’s best dressed woman, is featured in the ad campaign wearing a colourful dress which is unusual for the actress who regularly opts for a more muted colour palette, yet she retains her signature edgy style by wearing black heeled loafers, paring down the girlishness of the outfit, and her hair in loose tousled waves.

The fragrance, entitled “Florabotanica”, contains notes of vetiver, amber and caladium-leaf accord, rose, carnation and mint accord. Balenciaga designer Nicolas Ghesquière described it as vivacious, saying “There is something natural about it, it’s very alive.” I think that as a young person wearing it, considering that I’ve never worn a scent, it kind of puts you on this level of, like, whoa, check me out."

Ghesquière told WWD that he had Stewart on his radar long before she became the highest paid actress in Hollywood, according to Forbes. The designer said he has been impressed with her since 2002, when she played Jodie Foster’s daughter in the thriller “Panic Room”.

“I remember thinking, wow, I would like to do something with her one day,” he said. “She’s so Balenciaga”.

When the thespian was chosen to be the face of the new fragrance back in January, she dubbed the Spanish house “just cool”.

“Even when I first began to consider fashion and admittedly rarely knew the brand I was wearing, I always recognized and loved Balenciaga,” she said, adding, “I feel drawn to it. It provokes on a number of levels. It isn’t afraid or contrived.”

Over recent months, Stewart has been acclaimed for making the transition from awkward teen to fully fledged fashionista, frequently opting for attire that is both chic, edgy and sets the fashion world buzzing, especially for her comfort over sophistication footwear choices, in her trusty converse.

The new fragrance launches in autumn 2012.
