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.

The actress looked impeccably chic at the screening of new flick Stoker in London on Sunday.
She showed off her stunning figure in an indigo, hot-off-the-runway L'Wren Scott dress featuring a gold sequined turtleneck collar.
23-karat gold leaf L'Wren Scott pumps, a slightly messy chignon, and gold hoops completed the elegant outfit.
