Last week Emma Stone rocked a daring black and white polka-dot gown by Luca Luca. Her fashion risk paid off, since 68 percent of Us Weekly readers said they loved the look.

The 22-year-old continued her unique style streak when she hosted a dinner for Giorgio Armani and Vanity Fair on Tuesday in Los Angeles wearing a strapless metallic striped ombre dress with gathered detail at the waist from the designer's Spring 2012 runway.

She paired the ensemble with taupe Brian Atwood pumps, a loose updo and silver eye shadow.

In addition to starring in several hit movies this year, Stone was recently named one of the new faces of Revlon.
