Sienna Miller, the style center at the Cannes Film Festival

This year, Sienna Miller is part of the grand jury at Cannes Film Festival. Along with Sophie Marceau, Jake Gyllenhaal, Rossy de Palma and jury presidents Joel and Ethan Coen, Sienna Miller seems to be the chic feminine part that plays an important role in judging films this year.

"I don't feel worthy of judging these films. I will say what I thought was brilliant and be supportive. It's a huge responsibility because, of course, whoever wins these prizes, you know, their life is transformed, so I definitely feel the weight of it," she says. 

Her style has passed through different changes along the years: from cool to boho and now more minimalist style, the actress knows how to shine on the Red Carpet. And for the Cannes Film Festival, the right stylist is there to help her. Kate Young chooses the best outfits for the actress.

"I have a really strong sense of what I like and I think she's amazing," she says. "You have to bring it, because it's Cannes. You can't be in your pajamas, although I did ‘pajama' it this morning to the 8.30 a.m. screening and got away with it," the actress adds.

In any way, she brings more light and smiles to the jury with her beauty and feminine chic look.
