To use this costume, first put on the jumpsuit. Then, fasten the belt around your waist to give it a more authentic look. Slip the cuffs onto your wrists to complete the Black Widow style. When wearing it, make sure all the parts fit well and are comfortable. Avoid rough play that might damage the costume. For maintenance, hand - wash the jumpsuit, belt, and cuffs in cold water with mild detergent. Hang them to dry, and don't use a dryer as it may shrink or damage the fabric. Keep the costume in a cool, dry place when not in use to prevent any mold or mildew growth.
