Weirdly Popular Halloween Costume in Each State

If you're going to a costume party this year, chances are you're not trying super hard, but you also don't want to be in the same costume as someone else, so we'll make it easy for you.

All you have to do is check which state you're in, and read what Zippia found to be the most popular costume in your state, and then just don't dress in that costume.

One that confuses me is why Mermaids are so popular in South Dakota. Is there some sort of oceanside tropical paradise up there I don't know about?
