The 27-year-old Scream Queens star attended Mulberry's "Beyond Heritage" runway show at the Spencer House in London, England, on Friday, stepping out in a cobalt blue ensemble that undoubtedly turned heads.
The actress went bold for the stylish soirée, rocking a long, sophisticated blazer, which she paired with tailored shorts of the same hue. She styled the chic pieces with ankle-strap heels and a vibrant bag, keeping her beauty look simple with subtle waves and natural makeup.
Roberts sat front row for the presentation, alongside Julia Restoin Roitfeld, Mary Charteris, Amber Anderson, Emma Greenwell, Andrea Riseborough, Jourdan Dunn and Millie Brady, who all looked equally fab.
The blonde beauty later took to Instagram, sharing an artsy shot of herself all dressed up and ready for the show.
"London I love you," she captioned it, tagging @mulberryengland.
