Greetings again children of chaos.
I was hoping i could gain some assistance in a costume i am planning on making of a chaos space marine for supernova comic convention next year.

here is a small picture of one i found on the internet.

I got told that foam covered in plastic is an option, i was just wondering if any experienced costume designers could point me in the right direction of the type of materials needed to make the above type of costume. Remembering that i would prefere it to be light and relitivly manovarable.
Thanking you in advance.
Primarch Lorgar.
