Star Style at Sundance Film Festival

With this year's Sundance Film Festival now at its halfway point, hundreds of celebs have flocked to Park City, Utah, to participate in the week's festivities. Between film screenings, events, and parties, our favorites in Hollywood are stepping out in their chicest winter-wear. These seven stylish ladies won us over with their oversized pea-coats and worn-in biker boots.

Our favorite child-star turned leading-lady, Dakota Fanning, stepped out in Park City wearing boyfriend jeans, a camel pea-coat, and cat-eye sunnies. Earlier in the week, the star put aside her casual street style for a Louis Vuitton skirted number at the premiere of her film, Very Good Girls.

The whole beanie-tee-skinny-jeans combination is an eternally great choice for chilly weather. We're simultaneously impressed and jealous that Jessica Biel looked so effortlessly cool in this street style outfit, complete with some serious fringe boots and ombre locks.

The very pregnant Kristen Bell was all smiles in a turtleneck sweater-dress and messy fishtail braid as she promoted her new film, The Lifeguard.

Star Naomi Watts is having quite a year, first for the multiple noms for her role in The Impossible but also for the Sundance premiere of her upcoming film Two Mothers. Here, she kept warm in chic sneakers, wrap-around scarf, and stylish parka.

Evan Rachel Wood rocked an all-black tuxedo jacket look at the premiere of her new film, The Necessary Death of Charlie Countryman. Her super-short, tousled blonde 'do was perfectly paired with light, rosy makeup.

At the premiere of Don Jon's Addiction, star Julianne Moore looked slim and stylish in a pair of leather pants which she paired with a dainty blouse. The signature redhead wore her hair in a topknot, giving the look a casual yet put-together vibe.

Promoting Ain't Them Bodies Saints, actress Rooney Mara also opted for the all-black aesthetic, including a cropped oversize sweater and trouser pants. Her slick hair and clean makeup added a nice contrast to the ensemble's otherwise heavier feel.
