Bette and Dot Tattler From American Horror Story: Freak Show
What to wear: If you can find a second head, or make one out of papier-maché à la Michael Scott, you've got this one nailed. Go with a simple headband for both of you and a pretty dress.
How to act: It really depends on whether you want to be Bette or Dot. If you're Bette, you're a little in the clouds, and if you're Dot, you're no-nonsense.
