Using your Darth Vader kids costume is easy! First, put on the chest piece and fasten it securely. Then drape the cape over your shoulders for that iconic look. Slip on the mask to complete the transformation into the fearsome Darth Vader. When you're ready to battle, take out your lightsaber and extend it up to 3 feet. Be careful when extending and retracting the lightsaber to avoid any accidents. When you're done using the costume, store it in a cool, dry place. You can gently spot - clean the chest piece and cape with a mild detergent if they get dirty. The mask should be wiped clean with a soft cloth. Make sure to keep the lightsaber away from water to prevent damage.
