GundamVader

Hello everyone! I'm Chris from Los Angeles County California, and a friend of mine already in 501st got me interested and I've had this idea for a while but after seeing a bit more at a meeting I want to try and actually build this costume to life. I wanted to build a Sith Trooper from the original Knights of the Old Republic game, so basic trooper but thought it'd be a fun build plus don't think I've ever seen any around. Would any one have any suggestions for where I should start to find the parts or a way to get pieces of the armor together? Much appreciated! A bit more about myself, I've never done a Star Wars outfit but I've done my own Raiders of the Lost Ark Indy outfit for cosplay and I've also built a small BB8 unit that I use for car shows with a remote controlled head and sounds.
