There's something to be said for a singer or band who can compel their fans to not just buy a T-shirt or sticker or button, but to actually dress like them, as well. Usually these fanatics, as a whole, earn a nickname like Army or Legion or Nation. With the pop's latest cult leader, Lady Gaga, the fans are known as Monsters. And the fans go to great lengths to mimic her dress from awards shows, music videos or album covers. Here are the 21 or so best look-likes from last night's Lady Gaga concert at the Pepsi Center and the after-party at Tracks.

Each look-alike is rated on a scale of one to five Lady Gaga heads, 5 being the best and 1 being, "meh."
