Who: Margot Robbie

Where: The New York premiere of Martin Scorsese's "The Wolf of Wall Street" at the Ziegfeld Theater, sponsored by Giorgio Armani.

When: Tuesday, December 17th

What: A white, one-shoulder Giorgio Armani Privé gown with black beaded detailing and pearl, diamond and gold spider earrings and a diamond and gold full-finger ring, both by Jacob & Co.

Why: As a relative newcomer, the Australian actress, who stars in the film, was smart to edge up a classic Hollywood dress with subtly rock 'n' roll hair, makeup and jewelry.
