As a cosplayer, I can appreciate all of the time and labor extensive process that goes into constructing and repairing the Disney Park costumes. Mickey Mouse alone has over 230 different costume outfits, for every occasion, season and event. Princess Belle has four different dresses.
Not only are there character costumes for meet and greets, there are parade costumes, stage costumes and cast member uniforms.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
