8 Things Celebrities Always Wear at the Sundance Film Festival

When in doubt, layer it up. AnnaLynn McCord demonstrates how to do it, topping a red flannel with a warm-but-cool leather motorcycle jacket. 

Sophia Bush proves that it is indeed possible to stay warm and look cute in this sweater made of the softest baby alpaca.

Trudging up and down Main Street is no occasion for silk pants. Instead, try these durable 3x1 jeans—as seen on Nikki Reed—which have a flattering high-rise fit.

Footwear is tricky territory in Park City, where itineraries require dashing from slopes to screenings. Take a cue from Jessica Chastain and opt for Sorel's versatile (and waterproof) wedge boots, which elevate—pun intended—the workaday form. 

Sub-zero temperatures call for a really warm coat. Per Ellen Page, this water-resistant Canada Goose jacket with fleece-lined pockets fits the bill. 

The Sundance look is decidedly casual, and nothing says "I'm not trying too hard" more than a backpack. This bright blue mini style, worn by Lena Dunham, is also water-resistant. 

There's no better way to keep your ears warm than with cashmere. Brooklyn Decker knows what we mean. 

Many celebs attempt to go incognito with oversize sunglasses. Imogen Poots's pick? A classic pair of Ray-Bans.
