Olivia Munn looked regal at the Metropolitan Opera's gala premiere of Rossini's "Le Comte Ory" on March 24 as she dazzled in a floor-length black velvet Yves Saint Laurent gown.

The "I Don't Know How She Does It" star may be a relative newcomer to red carpets, but she's already showing her fashion mettle. The star's strapless dress fit like a glove, and didn't need any extra embellishment besides the belt which clasped in a silver bow at the back.

Munn simply added a pair of opera gloves and a black velvet clutch to her ensemble. She was joined at the event by the Olsen twins, Claire Danes, Julianna Margulies and Claudia Schiffer.

Like Munn's bob haircut? See who else debuted the 'do recently.
