If you want to survive in the deserts of Arrakis, you’ll need a stillsuit. Sometimes it seems like you need the wearable exchange system to get by at a comic convention. DeviantArt user J-CashMD made a Stilgar costume to wear at Denver Comic Con last year, and he won second place in the craftsmanship competition. He started with the base of lycra bodysuit:

First pieces of neoprene glued on a lycra bodysuit.
The body suit has been predrawn with dimensional paint “tubing” in some locations
Material is fabric coated neoprene, 1/8″ thick
Glue is DAP contact cement
Once completed, the whole thing has to be coated with latex paint; a black base (multiple coats, this stuff drinks paint up), and a thin top layer of metallic brown to give a “sand-impregnated” look. Then rubbed with real sand and cinnamon (for that melange spice scent!)
