These adult Blonde 70s Guy wigs are a great accessory for 100s of 70s costume themes from the cheesy 70s TV cops and detectives to awesome Will Farrell's character in Anchorman - and great for anyone who just wants to have more fun. These are 100% synthetic wigs, can be washed, and can be worn without a wig cap, although wig caps may help depending on how much hair you have.
