now you want me to dress up? Spooky dating/fashion moments!

You have been invited to a Costume Party...how do you ask someone to be your date for an event that will make them rent a costume or have him/her in a itchy wig all night? The costume shop is not cheap! A good costume could set you back a few hundred bucks? How do you accompany someone to such an event for under $100? If asked, it has to mean your special or does it? Do you really want to go in the first place? Don't be scared....
