Yes, Brad Pitt [1] and Leonardo DiCaprio [2] were at the Once Upon a Time in Hollywood UK premiere [3], but it was Margot Robbie who brought the heat in a fiery Oscar de la Renta gown. As the rest of us slowly start to face the end of Summer, the 29-year-old actress jumped right into Fall colours with a purely autumnal colour palette on the red carpet — not that you can confuse her outfit with cosy sweaters and boots.

Margot's burnt-orange gown, from the Autumn/Winter 2019 collection, featured a plunging neckline and gaping cutouts along the upper sides, with a wraparound scarf detailing. Now, that's one way to combine Summer and Fall trends into one. The skin-baring top came with a flowing skirt and train, which gave Margot a goddess-like appearance as she posed for photos. She completed the gorgeous outfit with dangling earrings, a massive gold ring, a reflective Edie Parker clutch, and metallic heels.

Costars Brad and Leo complemented Margot's ensemble well in their dapper suits. Brad opted for a navy blue coat and trousers with a black sweater underneath, while Leo kept things classic in a charcoal set and sunglasses. They make a suave trio, indeed! Ahead, see every angle of Margot's evening out and zoom in for a closer look at her incredible matching makeup.
