Margot Robbie just shut down the War Child Gala in London with a jaw-dropping one-shoulder black gown. She kept it classic with strappy rhinestone heels and simple glam, but the internet can’t get over how elegant she looked. Pics of her with Carey Mulligan and Emerald Fennell are all over social, and fans are obsessed—comments range from 'simply spectacular' to 'very elegant.' If this is a preview of her Wuthering Heights promo looks, we’re in for a treat! #Beauty #MargotRobbie #RedCarpet
