For Amy: Normally in geeky attire, Amy's outfits rarely change, but this Halloween, you could dress up just like Amy did for "The Big Bang Theory"'s finale. A lavish dress with lace and feathers will be needed as well as her iconic glasses.
For Sheldon: If you want to win a Nobel Prize this Halloween, dressing up as Sheldon Cooper will do the trick. Wear a tasteful suit complete with a white bow tie, and finish off the costume with your finest gold medal.
