The actress, 35, walked thered carpet for the premiere ofThe Chronology of Waterat the 78th annual Cannes Film Festival on May 16 in a look that was equal parts chic and relaxed. For the occasion, Stewart wore an all-white Chanel suit, consisting of a fitted white jacket, trouser shorts and a sheer white blouse with a tiny black tie. TheTwilightalum added a sensual touch by leaving a few buttons open, daring to break the festival's no nudity rule. ("Nudity is prohibited on the red carpet, as well as in any other area of the festival" due to "decency reasons," theofficial FAQ website for the eventreads.) Instead of breaking dress code on the red carpet, Stewart opted to let her brand-new leg tattoo steal the show. The shorts showed off the ink, located just above the knee, that read "MINE" in all capital letters.

And then this song comes on and it goes, 'Mine, mine, mine, mine.' And it's just f------ mine," she revealed.
