The Jacket

I have a feeling this might be the hardest part of the costume. I have an idea for it, but I don't know how easy it will be to acquire something that fits what I have in my mind. I might just go simpler and instead of keeping the theme of purple/gold zebra print going I'll use a solid color instead. Originally I was thinking purple, but now that I think about it, how would a nice shiny gold jacket look?
I could just use something simple and cheap like this. Technically I'd have to damage it to do what I want with the jacket though. And $50 isn't a cheap mistake if I do something wrong. I think I'm going to start checking out some thrift stores.
