What Are the Top Picks for Halloween Costumes This Year?

From villains to vampires, Americans plan to go all out on their Halloween costumes this year. HowStuffWorks

Despite the creepy clown sightings and the imminent U.S. presidential election, many Americans still plan to party on Oct. 31 – more than 69 percent, according to a survey from the National Retail Federation (NRF). People in the U.S. are expected to spend a whopping $8.4 billion on candy, decorations, costumes and the like for the spooky holiday, more than in any other year since the NRF began its survey.

Considering more than a third of that $8 billion is likely going to costume purchases, dressing for the occasion is not to be taken lightly. Let's take a look at the top costumes trends of the year. (Don't worry, clowns didn't make the list.)

Most Popular Children's Costumes

Coming in at No. 1 for children is the superhero costume, which ousted the princess costume from its 11-year reign. More than 3 million kids are going to dress as superheroes, while another 2.9 million will dress as princesses. Move over tulle, hello tights! Animals, "Star Wars" characters and zombies also placed in the top 10, proving that some costumes never get old.

Most Popular Costumes Adults 18-34

Among the millennial group (age 18-34), Batman characters are the most popular pick for Halloween garb inspiration. That includes Harley Quinn, the Joker and other DC Comics figures, and this comes as no surprise following the box office success of "Suicide Squad," one of the highest grossing movies of the year. More than 9 percent of millennials choose this option, followed by 6 percent who choose the witch costume. Slasher-movie villain costumes are also big in this age group, while perhaps a little too terrifying for younger trick-or-treaters.

Most Popular Costumes Adults 35+

Political figures are big among people age 35 and older – coming in as the third most popular option. But the No. 1 costume in this age group is something classic: a witch's hat and black clothing. Sometimes the simplest choice is the scariest choice.
