RO white smithas for making the armor... same procedure as above... but I suggest something more flexible, rubber sheet.
if you want to do the artwork one
1. for the base, buy leather gardening gloves in ace hardware... paint it brown with spray paint or acrylic (water based) cut off the finger tips
2. with upholstery leather make the straps and attach buckles... attach it to the rubber sheet.
or you can get an idea how to make it with cosplayer's costume... search the toy con pics... there was a female assassin there^_^
