Well, the dress has been found ... to be a fake!
The thief who took the gown says he took the dress from Lupita's room at The London after finding the door ajar.

Wearing looks from the spring and prefall collections, the two did their obligatory poses for the photogs before settling in to take in the show.
Jessica wore a belted maroon dress with simple black pumps, while Olivia was a little more striking in a black knee-length number with blue lace overlay and ankle-strap pumps.
An Iwona Ludyga bracelet completed Olivia's look, but Jessica left the jewels at home and accessorized with her glorious red mane.
And we really hope she saw some Oscar-worthy dresses at the show! Less than 10 days until the big event!
