Many Halloween costumes require a chest plate. Whether your child dreams of being a superhero, a robot or a gladiator, you can make his wish come true with a roll of duct tape and an old T-shirt. The resulting chest plate is custom fitted and can be decorated to suit any costume.

  1. 1

    Put the T-shirt on your child. It should fit closely to avoid bunching. Use a marker to draw the outline of your chest plate onto the T-shirt. It needs to have a front and a back, as well as arm and neck holes. The chest plate will be cut up the back, so it doesn't need to fit over your child's head.

  2. 2

    Use 4-inch pieces of silver duct tape to form the chest plate over the T-shirt. Build two or three layers so that the costume will hold its shape. Use additional colours of duct tape, if desired, to customise the chest plate. The chest plate will be worn closed, so make sure your child can take deep breaths and has a wide range of movement as your tape.

  3. 3

    Cut the tape and the T-shirt very carefully up the back from the bottom to the top. Remove the chest plate from your child. Trim away all exposed T-shirt material. Use additional duct tape to finish arm holes and neck hole. Bottom-hem and cut edges in the back.

  4. 4

    Decorate the chest plate to suit your costume with other colours of tape and coloured or black markers. When ready to use, put the chest plate back on your child with the cut to the back. Seal the cut with two or three crosswise strips of duct tape.
