This particular costume was a best-seller, but other outfits for both adults and kids taken from the live-action remake of Mulan were top in 2020. The Disney film was forced to have a home release due to the pandemic, but the story proved to be popular in inspiring Halloween costumes.

This costume was a top seller but other Black Widow catsuit outfits were also popular in 2020. The highly anticipated Marvel prequel movie was a hot title for 2020 that got pushed back due to the pandemic, but the strong female hero character remained popular for both kids and adults last year.

The optimistic, honey-loving cartoon bear would have been a great mascot for 2020. He's a little pudgy, he doesn't wear pants, and he's always trying to see the bright side of a situation.

In a year when we needed our first responders more than ever, doctors, nurses, police, firefighters, EMTs, and other frontline workers were popular costume choices in 2020.
