"Minnie Mouse has over 365 different individual special event and holiday costumes. I’m sure Mickey has just as many, it was just that they specifically mentioned Minnie.
Buzz Lightyear is the most expensive costume and NASA helped design it. It’s made from fiber glass and costs about $8,000. The cheapest costume is Eeyore at between $300-400 because he and the other Pooh characters are mostly made of carpeting."
