Some people work all year on their Halloween costumes, creating works of art, be it Voldemort or Sansa Stark. But you fans aren't the only ones who go hard on Halloween — your favorite celebs get into it too!

Carrie Ann Inaba absolutely stunned us with her costume for this week's Dancing with the Stars Halloween night! Honestly, she looks so much like the real Morticia from The Addams Family that we had to do a double take! Victoria Justice also dressed to impress as a human Ouija board, and her celeb lookalike Nina Dobrev seriously blew our minds with her hilarious A Star Is Born costume. She even added a "Campaigning for Best Picture" sign to her getup to make it more authentic. LOL!

The internet's new Netflix boyfriend, Noah Centineo, dressed as Gaston from Beauty and the Beast, making us reevaluate our hatred for that particular character. Honestly though, it's going to be next to impossible to beat Harry Styles, who wore a replica of Elton John's bedazzled Dodgers uniform from his performance at Dodger Stadium in 1975. Talk about dedication!
