Halloween Party costumes

What to wear to a Halloween party when the invitation requires a costume? If you are attending as a couple, how about a famous couple from tv or the movies? Singles can go as a pop star, cartoon character, politician, animal, food item, popular toy or stuffed animal? Perhaps a favorite team mascot or sports figure? Country western singer or a Broadway show star? Fictional characters? Song and dance team? A popular character from a children's nursery rhyme or fairy tale? Costumes from foreign countries? What have been some of your favorite costumes, either you have worn or have seen on others? Was there a theme to the party? What costumes were awarded prizes? Tell us some of your most creative costumes.
