She's been #WithHer since before the Iowa caucuses, but Perry took her support of Hillary Clinton to the next level with her insanely elaborate Halloween costume. Though her red pantsuit is standard Clinton attire, it's the prosthetics and makeup that really make her look part. Having her "Bill" — agent Michael Kives — at her side doesn't hurt, either!

Wherever Sia goes, she's incognito, so it's to be expected that a Sia Halloween costume is disguise-worthy, too! We never would have recognized DeGeneres under all that hair.

Dobrev may have been incognito as Lochte, but the man was pretty hard to recognize himself! He wore a bright orange wig and plenty of face paint for his costume as the Mad Hatter. Fiancée Kayla Rae Reid was a bit easier to identify in her matching Alice costume.

If you ran into Sampio on the street, chances are you had quite the scary Halloween. The model's rendition of Samara from The Ring was way too true-to-life for comfort.

Stewart has conquered all things home, kitchen and really, the world, so it's only time she takes on Hollywood, too. The domestic goddess made quite the transformation to an ultra-glam Marilyn Monroe.

What do you do when you want to celebrate Halloween with your bros, but you're also Leonardo DiCaprio and get accosted by fans wherever you go? Put on a mask-hiding mask, of course! DiCaprio went full werewolf (or Wolf of Wall Street) to take on Halloweekend with his friend Tobey Maguire.
