The iMustache iPhone app lets you add an assortment of different mustaches to any pictures or photos you take with your camera. The app features a wide assortment of mustache styles and colors including the classic Groucho Marx eyebrow/glasses/nose/mustache disguise. It also lets you resize and rotate the stache to get it just right.

Of course, the app will mostly be used to be-stache women, as demonstrated in the sample here. Men, on the other hand, can just grow their own.
