Interactive costumes are outfits designed to engage wearers and audiences through technology or physical features. These costumes often incorporate elements like lights, sounds, or movement, allowing them to respond to the environment or the actions of the wearer. This makes them popular for events like Halloween, theatrical performances, and cosplay. Many interactive costumes use sensors or programmable components, enabling them to change appearance or behavior based on user input. For example, a costume might light up when someone claps or play sounds when a specific motion is detected. This innovation enhances the overall experience, making costumes more dynamic and entertaining.
