In honor of Mila Kunis' role in Friends With Benefits, which hits theaters this weekend, we've taken a look back at some of her most memorable ensembles.

The Ukrainian-born actress has had a red letter year, which has included an acclaimed turn in Black Swan, a buzzed about GQ cover story shot by Terry Richardson, and most recently an invitation to the Marine Corps Ball by a smitten admirer. Next up, Kunis -- a huge Star Trek fan -- will reunite with her Forgetting Sarah Marshall co-star Jason Segel in The Muppets.

Since her That '70s Show days, Mila's au courant outfits have become strikingly more sophisticated. The effortlessly elegant actress favors bold color, feminine ruffles and structured silhouettes.

Which look is your favorite?
