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.

On the one hand, she's wearing so little! Gurl showed off basically EVERYTHING in an almost completely transparent custom Adam Selman dress!
On the other, she's wearing so much- the dress is made of over 200,000 Swarovski crystals!
And while RiRi obviously had the edgiest look of the night, she's also gorgeously old school Hollywood glam with a pink fur stole and a 20s-style headpiece.
No wonder she's this year's Fashion Icon!
