A formula which can be applied in order to make any Halloween costume, regardless of how plain or innocent, slutty enough to be given the "sexy" title by the Halloween costume industry. The formula, from the shoes up, goes as follows: fuck-me pumps or heels, stockings, a short skirt or booty shorts, and a top to indicate what the wearer is supposed to be dressed as. Accessories are optional.

To make a sexy police officer costume, we can apply the slutty women's Halloween costume formula: black fuck-me pumps, fishnet stockings, a blue miniskirt, and a blue button-up blouse with a police badge.
To make a sexy maid: black fuck-me heels, black stockings, black miniskirt, and a white apron.

Chad: Fuck dude! Did you get her snap?
