In PSP game Akiba's Trip, players must expose vampires by...exposing them. Ripping their clothes off reveals if the characters are vampires.

To promote the game, a maid costume similar to an outfit worn by an in-game bloodsucker is on display, inviting folks to strip it—or rather, flip up the skirt, revealing stripped knickers.

A sign on the mannequin points out that while stripping is okay, taking the maid outfit home is not.
