The Sundance Film Festival kicked off this week and celebs in attendance were forced to ditch the warm Los Angeles weather for a much chillier Park City, Utah. Fortunately, though, they were able to conquer the cold with stylish abandon by sporting unique head-gear and perfectly proportioned puffer coats.

TRENDY TOPPERS:

In Park City, Utah to promote independent film "Martha Marcy May Marlene" and horror movie "Silent House" Mary Kate and Ashley's little sister Elizabeth Olsen was wandering around Main Street on Jan. 22 wearing a red beanie hat, beige scarf and black jacket.

"My Idiot Brother" actress Zooey Deschanel kept her toes warm in a pair of Tory Burch jacquard rain boots while picking up some free swag at an event on Jan. 23. We also adore the ladylike swing coat and adorable earmuffs.
