Using this Sub - Zero costume is super easy. First, put on the pants with the attached shoe covers. Then, slip into the tunic with the foam shoulder armor. Finally, place the headpiece with the foam face mask on your head. When you're wearing it, you're ready to show off your Mortal Kombat skills! As for maintenance, it's best to spot - clean the costume with a mild detergent if it gets dirty. Avoid machine - washing as it might damage the foam parts. Store the costume in a cool, dry place when not in use to keep it in good condition. And always be careful not to tear the fabric or break the foam pieces while wearing it.
