The most popular Halloween costume this year may not surprise you, but a few of the others definitely will.

Each year's Halloween costume trends reveal quite a bit about what's on the minds and in the nightmares of the country as a whole. This year is no different, though there are a few surprises.

Wonder Woman and Belle both had hit movies this year, and the very popular Stranger Things is returning to Netflix on October 27th. The new version of Stephen King's It has proven to be a monster hit and made Pennywise The Dancing Clown a star.

The oddest costume on the list is the giraffe costume, but it might be due to the video of a giraffe giving birth that went viral earlier this year.
