There are many occasions when a child may want a suit of armour--Halloween, a school or church play, or just for playing soldier at home. You can make a simple suit of Roman-style armour in about an hour at very little expense. You can also make an optional shield and sword.
Cut two rectangles just large enough to cover your child's chest and stomach out of cardboard. Round off the edges. Spray with silver paint and allow to dry. Hold the cardboard pieces up to your child and connect with Velcro strips across the shoulders and on the sides.
Cut between eight and 10 strips of cardboard 3 inches wide and long enough to reach from your child's waist to his or her knees. Place the belt on your child, and glue the cardboard strips around it vertically to form a skirt. Trim the ends of the strips in a "V" shape. Spray the belt and cardboard strips with silver paint.
Draw a simple shield and sword on cardboard. Cut out and spray with silver paint.
Cut two slits on the sides of the neck opening on one of the T-shirts to make it large enough to fit around the child's waist.
Assemble the costume by having the child wear the unaltered T-shirt on his chest and the other T-shirt around his waist as a skirt. Buckle the belt with cardboard strips around the child's waist. Attach the two pieces of armour to the child's chest and back with the Velcro strips. Complete the costume with sandals.
