This part is pretty fun. It's great because I was able to imagine whatever I wanted to put on to the suit. I based it of a really big painters suit that was about 8 bucks from the hardware store.
I made up some elbow and knee patches out of silver lame and interfacing, making rippled waves with the sewing machine, then cleaning up the edges with a serger. I had to open the legs and the arms of the suit to sew down the patches.
