Oscars parties: Sofia Vergara, Heidi Klum, Elizabeth Hurley turn heads on the red carpet

The 96th Academy Awards took place at the Dolby Theatre in Hollywood, California, on Sunday night – but several stars showed out at the award show parties.

Vanity Fair hosts an annual Oscars party, which Sofia Vergara and Jessica Alba attended.

Vergara, 51, stunned in a form-fitting, black gown. The "Modern Family" star's dress had a deep-plunging neckline and a cut-out on her torso. The gown had subtle, black bow details on the front.
