In case you missed it, one of the most highly anticipated summer movies has embarked on an equally delightful press tour. When you have a style star like Margot Robbie join forces with Hollywood legends Brad Pitt and Leonardo DiCaprio, you know the red carpet looks for Once Upon a Time in Hollywood will be nothing short of stellar. Robbie certainly hasn’t disappointed, but we were actually particularly obsessed with her after-party look.
Attending a post-premiere party in London, Robbie traded her Oscar de la Renta gown for a Matteau matching set that looked like the chicest pajamas imaginable. To make the lounge pieces look party-ready, she added Loeffler Randall Penny Mules ($395) et voilá: Robbie created arguably the most comfortable yet chicest party look. Scroll down to see what she wore to the Once Upon a Time in Hollywood after-party.
