Using this Darth Vader costume is super easy. First, put on the black lycra jumpsuit through the back zipper. Make sure the attached foam pieces on the chest, shoulders, waist, and legs are in place. Then, tie on the painted latex belt around your waist. Next, attach the black lycra cape to the back of the costume using the velcro. Finally, put on the hard - plastic mask by securing it with the velcro at the back. When it comes to sizing, always refer to the Rubies size chart to ensure a proper fit. For maintenance, it's best to hand - wash the lycra parts in cold water and let them air - dry. Avoid using harsh chemicals or bleach. The foam pieces and the mask can be wiped clean with a damp cloth. Store the costume in a cool, dry place to prevent any damage or mold growth. Have a great time cosplaying!
