Using this Barbie exercise costume is super easy. First, put on the blue lycra bodysuit. It's stretchy, so just pull it up over your body. Next, wrap the hot pink belt around your waist and tie the ends to make it fit. Then, place the blue headband on your head so that the Barbie logo is visible on the side. Finally, slip on the leg warmers over your calves. When it comes to maintenance, hand - wash the bodysuit, headband, and leg warmers in cold water with a mild detergent. Hang them to dry. For the belt, you can use a damp cloth to wipe it clean. Keep the costume in a cool, dry place when not in use. Make sure not to expose it to sharp objects to avoid any tears. Have fun dressing up as Barbie!
