Those would work really well, but the sizing would be an issue. It says it clear off the bat on the amazon page, and I'm a guy, so the fact that it's a woman's shoe makes it even more difficult.
I don't have much money to spend on this really. I've mostly got a lot of green and brown fabric, gold fringe-highlight material, fake leather, and buckram. I don't want to have to buy much more. The footwear is always an issue with every costume for me...
