Don’t overspend on Halloween accessories for you child’s costume this year. Skip the discount and costumes stores and instead head to The Dollar Tree. They have a wide assortment of accessories for pirates, knights, princesses, and many other popular costume themes. You’ll find tiaras, swords, shields, and other great costume add-ons like the ones we have pictured here. My son (pictured below) put together his entire knight costume for just $5. Not only that, they’re also a good source for party decorations, candy, cards, and anything else Halloween-related.
