Meet Breakout Style Star Lupita Nyong'o

Not only has actress Lupita Nyong'o captivated audiences with her critically acclaimed performance as Patsey in 12 Years a Slave, but she's also become Hollywood's newest style star thanks to her multiple, truly stunning red carpet looks to promote the Steve McQueen-directed film.

Check out five of her most talked-about appearances so far!

First up is this gorgeous yellow J. Mendel gown she wore to the 17th Annual Hollywood Film Awards, which showed off her flawless skin and toned arms. Bold orange lipstick and copper eyeshadow completed her flawless look. 

Lupita first got the attention of fashion critics at the 12 Years a Slave premiere during the Toronto International Film Festival, where she stole the show in a long-sleeved Prada gown. Gold sequins added intricate detail to the show-stopping white gown, which came complete with an understated train.

Yellow is clearly her color!  Lupita showed she can also rock a more casual look to perfection at the 12 Years a Slave press conference during the 2013 Toronto Film Festival. Lupita sported an eye-catching neon yellow Honor sweater, which she paired with floral shorts.

Lupita didn't disappoint at the Los Angeles premiere of 12 Years a Slave held at the Directors Guild Of America, where she was marvelous in Miu Miu. She elevated her look with standout makeup -- specifically, a purple lipstick that perfectly complemented her vibrant dress.

Lupita was once again radiant at the Fox Searchlight party at the Toronto International Film Festival, sporting a bright orange Antonio Berardi dress and a sassy pair of animal-print Christian Louboutin pumps.
