Johansson stuck to a simple all-black style for her after-party appearance, so she needed a hairstyle that would get her noticed. This rather complex-looking updo did the trick. It was slick and structured, thanks to the curled ballerina bun and subtle side plaits, and very on trend. (Twists and knots were seen on the Chanel and Chloe Spring/Summer catwalks).
To finish her vintage-inspired look? Red lipstick and a heavy coating of eyeliner. Good work, Scarlett.
