Start with a childs size black T-shirt and large purple T-shirt.
Use black duct tape to pucker up the top sleeves of the black shirt. Then take the large purple t-shirt and cut off the sleeves and neck to create an open square cut neckline. Cut points in half to make a fringe at the bottom.
Lay the bottom of the purple t-shirt into the bottom of the black t shirt. Pucker the purple shirt to fit and use orange duct tape to tape together. Continue taping a belt approximately 4" thick. Create a "V" shape to the belt when taping.
Make a sheet to duct tape by placing pieces together, cut out shapes to make a spider and stick to the orange belt. Add white and black circles to make the eyes. Cut out and place a dozen black circles around the waist band for decoration.
Cut orange duct tape into thin strips and use to make lace looking x's down the chest of the black t-shirt.
Use a large sheet of paper and roll into a cone, cut the bottom straight.
Take another sheet of paper and draw a large circle. Cut a hole in the center of the circle and slide the hat over the ring. Tape the hat to the ring.
Cover the entire hat with black duct tape. Use a bit of purple duct tape wrapped around the base of the hat and make a buckle if desired.
