Oh god, it took forever. It's such a tedious task! I need a sewing machine.
The orange parts of the armor are just orange fabric, the silver is mostly some kind of satiny material (which was a terrible pain to sew, good lord it tore so easily). I painted some silver details on, however, as well as some black details. The skin is some kind of denim-like material. It's kind of like a denim mixed with a metallic kind of fabric, it's not as soft as denim. I wish I knew more about these things...sorry!
