It's Halloween! That can only mean two things: 1) Scary things that go bump in the night, and 2) girls wearing senselessly provocative outfits. Oh yes, girls in so-called sexy costumes have become as much a Halloween tradition as pumpkin carving.

Now, we're not complaining that there are scantily clad women during the Halloween season. Not at all. The thing is, some of the costumes are trying just a little too hard. You know, when you look at the costume and think to yourself, "I didn't think it was possible to sexy up Optimus Prime." Well, you can! Here are 10 that really do exist:

  1. Bacon Dress
  2. Beetlejuice
  3. Ghostbuster
  4. The, um, Joker?
  5. Ketchup
  6. Sexy Spongebob
  7. Spider-Girl
  8. Miss Leatherface
  9. Sassy Tigger
  10. Optimus Prime
