The Spring 2018 Brock Collection dress, which would serve as the perfect cool girl wedding dress FYI, featured a structured bodice with puff sleeves and lace trimming along the neckline. The romantic gown perfectly suited the actresses signature boho style, while keeping in line with the dreamlike film she's promoting.
Margot complemented the look with rosy lips and cheeks, bold yellow eyeshadow, and floral diamond drop earrings. She styled her sleek new bob with an on-trend wet-look.
Margot was joined on her elegant stroll down the red carpet by her co-stars: the fabulous Domnhall Gleeson and the truly adorable Will Tilston.
Goodbye Christoper Robin is set to hit cinemas on the 23rd of November.
