Margot Robbie and Sophia Kerr
Speaking of absolutely terrifying costumes, you should definitely run the other way if you see Margot Robbie and Sophia Kerr walking towards you. Dressed as the infamous and creepy twins from The Shining, the two actresses were a scary sight to behold.

Sure, dressing as creepy twins is not the most original or unique Halloween costume out there, but that doesn’t make it any less terrifying. I wouldn’t want to be alone in a long hallway with these two, especially because their execution of the costume was so well done and terrifying.
