Star Wars The Force Awakens Chewbacca Electronic Mask with homemade costume SZ 5

My sister in law came up with the costume to go with the mask. The pants are a 5 seem with elastic in the back. A leather belt was cut and attached to the legs. Needs some glue to reattach a small area. One knee has a dirt mark from falling. I’m not sure about the vest. The mask alone is worth at least $20.
