How to Be Single may be a hilarious romantic comedy that focuses on a group of gal pals, but at the film's UK premiere, Dakota Johnson [1] was the one to steal the spotlight [2]. The actress wore a custom Marc Jacobs gown that was elegantly draped, loosely hugging her curves as its train swept across the red carpet.

While the design is made from a crinkly silk that, for some, might not be easy to pull off, Dakota emitted pure elegance. Even as she and her costars — including Alison Brie [3], Leslie Mann, and Rebel Wilson — huddled under umbrellas [4], shielding their gorgeous dresses from the rain, Dakota still managed to achieve the sultry, stylish look she was going for. Read on for an all-angles view of her slinky number and take in all the little details, from her ruffled sleeves and Charlotte Olympia heels to her Messika diamond earrings and cuff.
