A style star is born!
If Margot Robbie keeps this up, she's gonna be on all the best-dressed lists without a doubt!
Her one-shoulder Armani Prive gown fit her so well, it looked like it was sculpted right on her body!
The 23-year-old also knew how to WERK! She posed like only a supermodel could!
Completing the look with Brian Atwood shoes and Jacob & Co jewels, Margot totally stole the show.
Flawless first premiere outfit!
