My 3 year old son is obsessed with space. He spouts off all sorts of facts about the solar system and universe. His favorite planet is Saturn. Of course, he requested a Saturn costume for Halloween.
We took a paper lantern and paper mached it for reinforcement. A hole for the head, a wider one for his body, and two arm holes were cut in it so that it slides on him like a shirt. We painted it with tempura paint. For the rings, we cut them out from a card board box and wrapped them in tin foil. Tempura paint was lightly brushed over them so they still sparkled but had a rainbow effect.
He’ll wear black pants and shirt under the costume.
