"At eBay, we're always looking to see how our data can help predict the trends that consumers are most interested in at any given time," says Zoher Karu, eBay's vice president of customer optimization and data.
"Around Halloween we've historically seen a nod to classic superheroes and storybook characters. This year, it's no surprise that superheroes are a popular costume for both adults, kids and even pets!"
He continues: "We expect to see lots of Han Solos and Yodas out on Halloween inspired by the upcoming Star Wars film. Additionally, classics duos like Mario and Luigi, and Minnie and Mickey stand the test of time. And for pets, it appears that the ferocious (lion), cute (panda) and human-like (superheroes and neckties!) top the list."
