The vampires, goblins, and ghouls all come out on Halloween, and so do the slutty costumes.

For decades, women have seized the holiday to show off more skin than is normally socially appropriate.

As All Halo's Eve approaches, we took a look back of the most scandalous Halloween costumes from the 1900s to the present day.
