Costuming and DisneyBound are distinct from each other, but both clothing related. Costuming/Cosplay is when you recreate a character’s outfit as accurately as possible. DisneyBound is making an outfit from everyday clothing that is inspired by a character. Adults are not allowed to wear costumes in Disney parks, except on Mickey’s Not So Scary Halloween Party nights. However, DisneyBounds are subtle and composed of actual street clothes, so they are allowed.
