Sometimes the very best Halloween costumes are the silliest, wackiest ones (or should I say quackiest ones). A duck costume, for example, although super cute when worn by a child, is just plain goofy looking when worn by an adult. You may want to look for a costume that has some kind of covering for the feet, since some costumes do not include footwear.
