Dianna Agron hit the red carpet at the The Olivier Awards at The Royal Opera House on Sunday in London in a regal white dress.

Dianna Agron’s Olivier Awards Look

Agron, who is best known for playing Quinn Fabray on Glee, wore a white vintage Alexander McQueen gown – opting to forgo the black that many of the Olivier Awards attendees wore. The dress featured pearl accents at the waist and neckline. Agron complemented the dress with Christian Louboutin heels and bag, silver Annina Vogel rings and a dark manicure.

 “This stylish friend of mine, @adriensauvage. Last night at the Oliviers,” Agron captioned a picture with designer Adrien Sauvage from the red carpet.
