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.

And she looked HAWT!
Wearing a very seksi high-neck Hugo Boss LBD and what appeared to be no makeup, the 43-year-old actress easily stole the spotlight from her male companions.
Christian Louboutin pumps and very simple updo completed her look.
We just adore this classy yet totally smokin' outfit! If you're going to look like this all the time Renee, please come out more often!
