Costumes are special garments or outfits designed to imitate scary beings, science fiction-inspired characters, super heroes, or cartoon characters. Costumes mainly portray the wearer as a type of character other than their regular persona and are used in special occasions such as Halloween or costume parties.
Toys are objects designed for play. Toys are usually a small representation of something familiar such as an animal, a cartoon character, a person or a vehicle. They are generally associated with children and pets, but it is not unusual for adults to collect or plays with toys.
