Final Fantasy VII
I made the shoulder cover out of padded denim and covered it with an armored shoulder pauldron made of rounded plastic. The orange brooch which is attached to it was made by cutting a circular piece of curved plastic and edging it with a thin layer of foam and plastic sheeting. The various other pieces of armor I also created out of foam and plastic, studded with plastic buttons and then painted silver.
The Ninja Star I made later as part of a prop experiment. Here is a picture tutorial detailing the process.
