These adult unisex blonde 'Punk Idol' Rock Star costume wigs are a great accessory for 100s of costume themes from Joan Jet to 90s grunge rockers and trailer trash - and great for anyone who just wants to have more fun. These are 100% synthetic wigs, can be washed and cold styled with hairspray, and can be worn without a wig cap, although wig caps may help depending on how much hair you have.
