Step 1) Acquire one of the many low quality scans of the original pattern, create your own pattern, or buy one off of someone who has made their own.
Step 2) Find a dye sublimator in your area to print the pattern onto white lycra miliskin.
Step 3) Cut off the excess lycra
Step 4) Line up your seams and use a serger to sew it together, adding two (or three) zippers running down the sides and under the belt.
Step 5) Sew kung-fu shoes or water shoes into the feet...or make your own custom soles.
Step 6) Make the webs. You can choose to use bottles of liquid latex and simply draw the webs onto the suit by hand, or you can create a CNC milled mold out of metal, ensuring you can have a 100% movie accurate costume. (You can also buy webs)
Step 7)...If you didn't just use simply liquid latex, pour Shore 30 (Or some other similar rubber compound) urethane into your newly milled mold, to create your webs.
Step 8) Take your perfect webs and paint the tops of them pewter, leaving the sides black.
Step 9) Using the same techniques used to create the webs, create the spiders for the front and the back and the eye frames...or just buy them.
Step 10) Put a tight metal mesh into your eye frames.
Step 11) Using superglue attach EVERYTHING you just made.
Step 12) Enjoy.
As you can see there is no easy answer because almost every step has options (Many I decided to omit for simplicity's sake). If you read that and are still really interested in making your own suit, you are going to have to do the research to see what each of these things will cost you, because things (Services especially) vary greatly from place to place.
Good Luck.
