Star Winter Style at Sundance

Actress Malin Ackerman may not look like a chic Hollywood star in this dressed-down outfit, but she certainly looks warm -- and not at all frumpy! Ackerman wore a short down puffer coat to the "happythankyoumoreplease" premiere on January 22, 2010 in Park City, Utah. She paired it with some skinny jeans and black winter boots.

Fergie attends the premiere of "The Romantics" during the 2010 Sundance Film Festival on Wednesday, January 27, in an outfit that perhaps her grandmother knitted for her? The tucked-in turtleneck is a little '80s for us, and not at all the sexy look we're used to seeing on the star. The oversized sweater does nothing to show off Ferg's figure -- those Cole Haan Air Caprice shearling boots may be the only savior in her outfit.

Michelle Williams looks chilly as she leaves the Eccles Theatre on January 24, 2010 in Park City, Utah. She wears a typically eclectic outfit -- an olive fur-trimmed coat (perhaps fake fur?), black tights, and brown ankle boots.

Juliette Lewis looks a hot mess at the Sundance Film Festival on January 25, 2010. The furry hat, the scarf, the boots, the jacket -- individually they might work, but somehow all together the effect is sloppy.

Actress Katie Holmes attends the premiere of "The Romantics" during the 2010 Sundance Film Festival on Wednesday, January 27, 2010 in Park City, Utah. She wears a wool pea coat, black skinny jeans, and black leather boots for a very New York look.
