Mary-Kate and Ashley Olsen's lil' sister Elizabeth was essentially an unknown until this past week in Park City, Utah at the 2011 Sundance Film Festival where she debuted two indies that she starred in—Silent House and Martha Marcy May Marlene. After screenings, the 21-year-old's acting chops were being applauded, even securing her a role in Rodrigo Cortes's upcoming thriller Red Lights, with Robert De Niro and Sigourney Weaver. Elizabeth's success is spilling over into her wardrobe choices, too. Check out the two-thumbs-up ensembles we found the baby Olsen sib stepping out in.

Winter Wonderland

Even in snow showers, Elizabeth looked fresh faced at the Sundance Film Festival on Jan. 22 in Park City, Utah. If she keeps it up (the acting and the flawless complexion), we see a beauty contract in this girl's future.

Chic On the Go

For the premiere of Martha Marcy May Marlene on Jan. 21, the up-and-comer smartly dressed up her basics with a leather orange bag and matching belt.

Short and Sweet

Looking a lot like her older sisters, Elizabeth rocked a retro mini V-neck dress with a brown belt and nude ankle strap shoes at a screening of Mao's Last Dancer in August.

Long Haul

Pre-haircut, Elizabeth emphasized her past-the-shoulders mane in a couture-y floor-skimming, oversize frock, which she wore to the Broadway opening night of Impressionism in 2009.
