The EXTREMELY short version... I bought some white 4-way stretch lycra and sewed rough versions of the parts (pants, shirt, etc.) Hemmed them in nice & tight where necessary. Took a water erase pen (JoAnn Fabrics), stood in front of a mirror, and sketched the breaks betweeen the red & blue on the fabric. Took them off, carefully cut along the lines and transferred those pieces to cardboard templates. Tweaked them a bit to make them symmetrical, added bleeds and cut the parts out of red & blue lycra. Sewed it all up, sketched webbing on with the same water erase pen, and applied it (while stretched) with mask making latex tinted black out of a fine tip squeeze bottle. Spiders & eyeframes are Foamies sprayed with a couple coats of black PlastDip & lenses are cut from a KMart brand grease splatter guard screen. Shoes are Kung Fu slippers. Of course, the long version is MUCH longer, & includes a lot of trial & error, but that's the basic process.
