ok mi amigo, it looks alot like Mando chest peice, along with Imperial guard stomach peices.... the bottom is vader, it just is.
i sugest maken this yourself, given no one has Kade armor. i could help given my Mando has simalar chest peices i made myself. Get Sintra, or PVC board. You get that looking in your yellow pages for a plastics place, calling them to see if they have what u want (i think its 1/8 u want) and then convince your mom to help you get it. it ran 60 bucks for me, but i had more then enough for 2 costumes, so you get alot. Then i hope you know how to use a dremel tool, if not no worrie just umm.. well practice? and if you don;t have a dremel i'm out of ideas
i will atempt to modify the WoL templates to fit you... so what S, M,L.. ??
as always, if i am completely insane tell me guys...
