Should I be Super Katie James for Halloween?

Super Katie James cape

I mean, I have a cape and all (pictured...the big purple thing taped to the ceiling), that I made years ago for a market table display. And I could wear some kick butt boots, and my bridesmaid skirt outfit, to be in total Katie James Couture. Otherwise, I'm a little tapped out in the brain, and don't want to spend the $60 at a costume store. What's a Recessionista to do?
