This Halloween, families are expected to spend nearly $8 billion celebrating the holiday. That’s a 50 percent jump since just 2005. And a lot of the money is going to costumes. Americans spend about a $1 billion on children’s costumes each year, and another $1.2 billion on adult costumes. How it all got started dates back to the Middle Ages. For the folks at the Theatrical Costume Rental in Minneapolis, 20 percent of their yearly business is done during the month of October. Duck Dynasty, What Does the Fox Say and Jack Sparrow are just a few popular costumes this year.
