Who: Riley Keough.
When: Wednesday, March 30.
Where: The New York premiere of her new series with Steven Soderbergh, The Girlfriend Experience.
What: A nude Dior Fall 2016 mini dress with nude heels and a black box clutch.
Why: With a slick center part, dark lips contrasting with the neutral color palette, and an off-the-shoulders silhouette, it's aloof, severe, and so, so chic. Dior previously tapped the model-actress to be the face of its Miss Cherie perfume in 2006, and she walked in the brand's Spring 2005 show. Ten years later, she still wears it well.
