The Sundance Film Festival kicks off this Thursday in snowy Park City, UT. The indie movie fest draws an eclectic crowd of celebs ready to hit the screenings, premieres, and of course, the slopes. Unlike other red carpet events, Sundance boasts a Winter scene that is distinctly cool, casual, and chock full of bundled-up looks. We love spotting our favorite A-listers in luxe layered-up ensembles, shiny puffer coats, chunky colorful scarves, sleek booties, and more. If Kate Bosworth, Naomi Watts, and Elizabeth Olsen's cold weather chicness isn't enough of an indication of how the festival's icier climate inspires glam Winter style, click through now to see how other stars have styled their Sundance appearances throughout the years.
