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.

Channeling her inner Ariel, the fierce rapper arrived at the Mermaid Ball in London rocking red hair, a purple sequin bikini top and matching tail.
Even though she's not your typical siren of the sea, Azealia still blew everyone out of the water with her under the sea look!!
Her outfit and hair are definite Halloween costume winners!!!
