Victoria Beckham Is Still Wearing Her Halloween Costume

Halloween is over, so can anyone tell me why Victoria Beckham was seen dressed like she was on her way to a costume party? Splashnews says she was dressed in all over black, and “didn’t say a word as she walked through to the security gate.”
Methinks she was posing as a “shadow” (after all, they are also all in black and don’t speak) and that she secretly loves Halloween candy. (Someone tell her to lay off for a while though, she’s starting to plump up.)
