A very fashionable crowd attended the Metropolitan Opera Premiere of Le Comte Ory in New York City last night.

The event was presented by Yves Saint Laurent, who dressed all the celebrity attendees.

Ashley and Mary-Kate Olsen (joint at the hip) opted for very different looks.

Ashley looked fabulous wearing a green stole over her black shift dress, whilst her sister wore a long and loose black polka dot dress with a grey sleeveless coat.

Ashley hair was styled into a chic updo. MK opted for a side-sweeping plait.

The sisters complete their looks wearing black pumps and carrying YSL clutches.
