Natalie Portman is more known for going for classic silhouettes when on the red carpet. But the actress shook things up a bit when she appeared in Cannes wearing a sheer black number.

The Rodarte dress was reminiscent of Portman’s Black Swan costume and featured a beaded V-neck and a sheer, paneled skirt that revealed her bum in black underwear.

But this was no wardrobe malfunction and the 33-year-old thespian managed to flash her skivvies while still appearing classy.

She completed her look with strappy heels, a simple bun and minimal make-up.

The Star Wars queen was on the red carpet for a photo call for her directorial debut A Tale of Love and Darkness and was joined by her co-stars, Amir Tessler and Gilad Kahana.

A Tale of Love and Darkness is a reworking of Israeli writer Amos Oz’ memoir, and tells his tale of growing up in Israel and how his life changed after World War Two.

The film is done entirely in Hebrew and is a very personal project for the V for Vendetta star who was born in Israel and who lived there until her family moved to the US when she was 3 years old.

Portman’s film has been getting mixed reviews. Some papers, like The Guardian, sang praises for Portman’s “assured, heartfelt debut” while others had a more difficult time with the fact that the film was in Hebrew.

With her film shown successfully in this year’s Cannes Film Festival, Portman can now focus on her next project, the biopic Jackie where she’s set to portray America’s beloved first lady.

And if Portman’s fashion choices at Cannes prove anything, it’s that she’s so appropriate for the role of Jackie. After all, the former first lady is a known fashion icon, something that Portman is also turning out to be.
