Isla made a surprise appearance at fashion’s big night, the Costume Institute Gala, in New York City last night! She looked her usual dazzling self in a blue strapless sequined gown by American designer Tory Burch, with statement purple crystal and diamond earrings by House of Lavande. Isla looks gorgeous!

Inside the event, Isla was seated at the Tory Burch table, and according to reports, her husband Sacha Baron Cohen was with her! They just didn’t walk the red carpet together. Also at the table were Beyonce and her husband Jay-Z, Kristen Bell (who Isla posed with on the red carpet) & Dax Shepard, Kanye West, and guests from CAA and Vogue.

35 photos have been added from the event (sadly none from inside the event – sorry!), most of which are in HQ – enjoy!
