Lupita Nyong'o proved once again that she's the queen of the red carpet Tuesday at the Los Angeles premiere of her film Queen of Katwe. All eyes were on the Academy Award-winning actress, who lit up the event in an ethereal floor-length lavender number and matching headscarf.

The 12 Years a Slave star, who first captivated the fashion world with a Cinderella-inspired powder blue Prada gown featuring a plunging neckline at the 2014 Oscars, channeled the same dreamy aesthetic with her winning Tuesday evening attire.

Nyong'o's lilac Elie Saab gown featured a pleated skirt, a few side slits, and a deep plunging neckline, which was adorned with rainbow-colored straps that crisscrossed in the back and cinched in the actress's tiny waist.

The 33-year-old accessorized her look with a matching lavender headscarf, delicate drop earrings and strappy black heels, before topping it all off with a lavender-hued eyeshadow and a swipe of fuchsia lipstick.

Queen of Katwe is set to hit theaters nationwide on Sept. 30.
