You might be able to find a few things you can use to make your own on Listia. Its a website where you bid with credits on auctions. Every now and then people post costume stuff as well as cosplays. Just about everything has been posted there. Everything is free, so its pretty cool. I use it all the time. So far, I've won a Legend of Zelda keychain, a lot of 40+ piercings, charms, piercing posts, paramore button pins, and a ps2 game. most items are listed under free shipping, but some aren't. Anyways, its pretty cool.
