To use this Captain Marvel costume, simply put on the all - in - one jersey. It's easy to slip into and will make you look just like the hero. Put on the gauntlets to complete the look. When wearing, make sure the costume fits comfortably and doesn't restrict your movement. As for maintenance, it's best to follow the care instructions on the label.
