Paris Hilton, Joan Rivers and Crystal Harris all channeled the Bangerz singer in what was easily the most popular costume of the pre-Halloween weekend. (Well, we could have told you that back in August as soon as Cyrus stuck her tongue out at the MTV Video Music Awards.)
In a decidedly more loyal take on the look, Hilton slipped into a onesie at Saturday night's Playboy Mansion Halloween Party in Beverly Hills, Calif.
Rivers, however, put a comedic spin on her getup, covering up in a sumo wrestler-like suit for a taping of her E! show, Fashion Police. We're sure the panel had plenty to say about the outfit she wore to twerk.
Playboy model Harris's costume was all about the accessories, though – and we're not just referring to the now-infamous foam finger. Husband Hugh Hefner completed her Halloween look (which they proudly showed off on Twitter) in character as the "Blurred Lines"-crooning Robin Thicke.
And what's Cyrus going as?
