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.

Rachel McAdams was dressed to impress at the Sherlock Holmes premiere on Tuesday and impress she did!
The actress stood pretty on the black carpet in a beautiful Marchesa Resort gown with a sexy draped back and long train.
This is so much better than Rachel's last attempt at wearing Marchesa.
What do U think of Rachel's red carpet look???
