They were a Hit at the Halloween party we went to.
Step 1: Making the bodysuit
To start with I had to wait around a bit till the used costumes started showing up at the thrift stores. Pretty quickly I found a soldier bodysuit with some padded muscles that would work. All I had to do was paint it.Several coats of tan and brown spray paint got the colors close.. a little flat black for shading. the body suit is not as shiny as the mask but that's the problem with a commercial mask.
Cut a couple of small triangles out of a piece of cardboard and use that as a stencil to put the pattern on the outer edges. I used a little brown and black spray paint. I don't have an airbrush so this is all spray cans. A little glue on the seams can hide the stitching.. I used Plumbers goop. One of the distinctive things about most of the Predators is the netting on the body. We used some plastic strawberry netting that I got for free from a relative. Stitching this to the body suit was very time consuming but we felt this would last better than gluing it on.
