If you are out of ideas and need a good costume idea for a group of three, why not try this easy rock, paper, scissors costume? It’s instantly recognizable if you think hard enough though separately it will be hard to identify the costumes. Each costume follows the same premise as a sandwich with a back and front sandwiching the costume wearer. Then it’s just a matter of cutting and designing the the front and back (more or less the same for all costumes) to match the rock, paper, or scissors. The rock costume in particular takes it up a notch with foam painted grey to match a rock’s bumpy surface.
