The wig is not plastic, it's yarn wrapped around foam tubes.  Unfortunately, it didn't cover all of my daughter's hair.  It's also kept sliding off.  Needless to say, I carried the wig the last half of trick or treat.  Also, the velcro closures on the back of the costume didn't stay closed without a safety pin.  Cute concept but needs logical revisions. I wish I'd read the reviews before buying.
