Showing off her gorgeous gams, Theron slayed in a scarlet eye-catching Givenchy long-sleeved, ruffled mini-dress with strappy red heels. The actress kept her look simple with a topknot, a necklace by EF Collection and a ring by Graziela Gems.
The actress also took to Instagram to share a pic from the event, captioning the snap, "Get your blonde on. It's #AtomicBlondeDay."
Atomic Blonde follows Theron as a bad-ass international spy. The Fate of the Furious star had to go through intense training for the film and ended up with bruised ribs, a twisted knee and even underwent extensive dental surgery after she cracked two teeth.
