The 501st Legion receives a lot of costume requests at this time of year. For the record, the guys DO NOT lend or rent out their costumes. The costumes are ridiculously expensive, and the guys (and gals) put a lot of time, money, and effort into customizing their costumes and fitting them to themselves. They are not available for borrowing or renting. Now, if you happen to know a guy personally, and he is willing to let you wear his costume, that's one thing. But in general, their costumes are not up for grabs, especially by strangers.
