Katy Perry Blue Wig: Presenting the deluxe quality blue Katy Perry signature wig. Our wigs are beautifully soft and silky and flow like human hair, made from 100% Japanese Kanekalon fibre, the most exquisite material on the market. The Katy Perry Blue Wig is inspired by the wig worn in the California Girls music video featuring long, electric blue curly design and straight, blunt fringe. Katy Perry has also been photographed numerous times on the World’s red carpets sporting this bright and bold style and is probably the most famous of her creative wigs. The hair is sewn onto an adjustable cap that will fit all sizes, no pins or tape required.
