1. Monster Halloween This seasonal shop (which opens in early September and closes in early November) receives new arrivals daily, and provides both spooky and fun offerings for the whole family (pets, included!). We love that the scariest costumes are housed in the "dungeon," so little ones don't have to worry about any unexpected frights. The staff get into the spirit and are all dressed up, and there's loads of accessories to choose from for those just looking for odds and ends to add to your homemade costume. Bargain hunters take note: Locations mark down all their costumes by half-price after October 31st—perfect for scoring next year's duds.

The dancewear section is perfect for picking out items to create a Sugarplum Fairy or Black Swan look.
