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.

They definitely picked the right girl!
Fresh off of London Fashion Week, the crooner arrived at The Wooly in a H&M tuxedo jacket over a custom black dress with long sheer panels that gave her a chic Morticia Addams vibe.
If we could snap, we would! LOLz!
Ch-ch-check out more pics of her ensemble (below)!
