A visit to this massive costume, prop and magic mecca can be overwhelming—luckily, the store provides a handy map of its two-level space. Off-the-peg costumes are conveniently organized by theme, so you can navigate your way from "Devils, Priests, Nuns" to "Hula," "Hippies" and "Horror." The huge stock means you’re bound to find something, whether you need an easy last-minute costume for a party (throw on a "Sex Instructor" lab coat, $19.99) or want to rent an elaborate ensemble such as a full suit of armor ($350, plus $2,000 security deposit). Accessories are equally comprehensive; the range of masquerade masks alone spans from throwaway $3 eye masks to elaborate $3,000 limited-edition Venetian styles. Get outfitted from head to toe—there are wig, hat and shoe departments—and complete your look with professional makeup application (from $10 for simple wounds to hundreds for a total transformation using prosthetics). If you're hosting a party, creep out your guests with an illuminated Bates Motel sign ($30) or a life-size Regan figure with glowing eyes and a fully rotating head ($300).
