Halloween // Costume ideas

Im hosting a birthday party and the theme is dress up as a movie / tv character. The thing is, I have no idea what to wear. I want to stand out but I don’t want the costume to be too hard to make. Also, the party will be during a winter night so I don’t want to freeze to death. Any ideas would be appreciated I don’t mind if it’s a cartoon character or anything I just need ideas. I’m tall and have long brunette wavy hair for reference.
