Natalie Portman TIFF 2015: 'A Tale Of Love And Darkness' Star Stuns In Christian Dior

Looking radiant in Dior, of course.

The 2015 Toronto Film Festival has officially kicked off, with actress Natalie Portman hosting the 4th annual festival kick-ff fundraising soiree on Wednesday evening.

For the occasion, the 34-year-old "A Tale of Love and Darkness" star and director opted for a floral Christian Dior dress (fitting, as she is the face of the brand), which featured long, bell sleeves and ruffled accents on the shoulders. Adding edge to the pretty frock was a metal ring appliques over the bodice. Portman finished off the look with black strappy sandals and a satin Dior clutch.

For her beauty look, the mother-of-one opted for a chic, slightly undone updo. Her face was fresh and glowing, with brown eyeshadow, bold lashes and nude lips completing her soft and sophisticated look.

Natalie will be unveiling her film, "A Tale Of Love And Darkness," at the festival this year, marking her directoral debut. The flick is an adaptation of the memoir of Amoz Oz, a writer who believed in and fought for a two-state solution to the Israel-Palestine conflict.
