Make sure you have pictures from all angles. I sort of mixed the first two pictures with my sketch. Get yourself some cardboard (they sell Tshirt form cardboard at craft stores) and some fabric paint. I painted half the shirt first to see if it would work. When it did, I painted the other half. If you are not a painter, you may want to get help for this. There is blending and painted technique necessary. I'm not much of a painter, but I figure with all the armor on, hopefully my mistakes won't be too obvious.
Once I had the front painted, I painted the back. Anything that is going to be covered in armor does not need to be painted, that's why there are non painted portions of the shirt.
Next, I painted the leggings. I made a duct tape dummy of my legs. Basically, wrap yourself in duct tape (use plastic or old clothing as a barrier) being careful not to pull too tight or you'll be lumpy. Cut yourself out, tape seams, and stuff. It's probably easier if you have help. I did not. Paint legs.
I painted more than what is shown here, simply forgot to take a picture. Sorry loves. And here is the finished product:
Not as good as painted skin or a latex suit, but you do what you can. Hopefully it looks amazing once put together with the armor and helmet.
Until next time, keep cosplaying! Any questions, comments, or request, leave them below!
