Trick-or-treating is more fun with a buddy — especially one in a matching getup. Your scary dragon will be storming castles (and front porches) with his sidekick, a stuffed pal wearing a mini version of his costume. Bee, pumpkin and puppy double disguises are other options; available in sizes include 0 to 6 months, 6 to 12 months, 12 to 24 months, 2T to 3T, 4 to 6.
