But for someone who won a "Break the Internet" award in part by posing in flashy naked selfies, Mrs. West looked awfully toned down (and absolutely gorgeous) for the occasion.
Wearing a black asymmetrical Vivienne Westwood dress with a thigh-high slit and strappy sandals, the 35-year-old ditched extensions and opted to wear her hair at its natural length.
In a snapchat taken aboard a private plane to Cannes immediately following the ceremony (of course), Kardashian-West explained that she wore "no fake lashes, no hair extensions, no lipstick, no jewelry" to the event, asking fans what they thought of her look for the evening.
But lest you think Kim's stepping away from her all-glamorous-all-the-time lifestyle, she also shared a photo of herself sprawled across the plane (still wearing the dress!), which she called "cramped" -- a statement we assume was meant sarcastically.
Hey, everyone has their limits, right?
