How would I make the chestpiece/breastplate?
The pauldrons?
The cape?
The boots?

I only have cardboard, duct tape, metallic spray paint, double sided tape, jewelery wire, and aluminun foil and the materials to paper mache.
It doesn't have to be spectacular.
Also, I'm a girl, so keep it in mind that I can't do the whole open chest thing.

Any help would be nice.

Thanks to everyone that answers!
