Between the hit Broadway musical and 2012 GOP candidates, Mitt Romney and Jon Huntsman, Mormons have a big year. Dressing as a Mormon missionary is a great way to tap into the phenom, and is an especially easy costume to prep. Just grab some business-casual clothes, slap on a name tag with the appropriate denomination (the Church of Jesus Christ of Latter-day Saints) and look abstemious. If you're feeling really ambitious, you can try to convert your fellow revelers. Or you might carry some engraved golden plates, as a nod to the tablets Joseph Smith said an angel gave him when he established the religion circa 1830. But be wary: if you're planning on partaking of the devil's brew, you best do it on the sly.
