Who: Zoe Saldana

Where: The premiere of "Infinity Polar Bear" at the Sundance Film Festival.

When: January 18th

What: A black Michael Kors sweater, white Tory Burch button-down shirt, black Goldsign high-rise skinny jeans and black fur-trimmed Robert Clergerie lace-up boots.

Why: Just because it's cold and you're in Park City, Utah, doesn't mean you need to be a style slacker. Saldana amps up a jeans and sweater ensemble with unexpected proportions—and still appears cozy and comfortable.
