One carnival celebration you should get excited about this summer is Katy Perry’s Prismatic tour. She will tour over three continentes and perform over 100 shows. I haven’t heard her entire album, but her song Dark Horse must be a chart topper. It plays about every 20 minutes on every pop hits radio station. However, I am guilty of singing along every time its on. Anyhow, what I am most looking forward to is an exciting and animated wardrobe. These designs by Roberto Cavalli above are only a teaser and are signaling a fashion forecast for Holographic fashion pieces.
