This costume is my latest creation. Most of the costume is thrift store clothing that I put together. I was fortunate to find an assortment that worked together. For the staining I used coffee, soda and shoe polish. I also misted the entire costume with a black temporary hair color ( like the sell at Halloween). There were a lot of images to go by. I tried to match the stains in the movie photos.
Unable to find stompers (boots), I had to use white sneakers with sock cuffs and elastic bands.
The pulse blaster was an important prop. I made mine from a toy blaster that I modified by gluing on pvc pipes and dowels that I then covered with craft foam and embellished with acrylic paints. The strap is a canvas belt. Because a 2 year old would be carrying this rifle it had to be super light weight and easy to carry.
