Margot Robbie joined her Barbie costars at the Faber & Faber Screenplay book party in Los Angeles on Saturday.

The 33-year-old actress put on a show-stopping display as she modeled a hot pink minidress with bows and peep-toe heels for the event.

At the star-studded event, the Babylon star — who was joined by her husband, Tom Ackerley, at a screening of Greta Gerwig’s hit fantasy flick earlier this week — left her honey blonde tresses down in soft waves.
