TO THE POWER OF TWO: “Twin power is in the house!” Dan Caten exclaimed backstage at Dsquared as Tokio Hotel’s twin band members, Bill and Tom Kaulitz, mingled with Caten and his designing twin sibling Dean. “I was really nervous beforehand,” confessed Tokio’s lead singer Bill Kaulitz, who opened the fashion show in skinny leather jeans and a feathered cape. Following a “bit of partying,” the German rock group will return to the studio to prepare its forthcoming Humanoid tour — “a robotic, futuristic sci-fi extravaganza,” Kaulitz assured. Dsquared is set to outfit the band, first noticed by the Catens at an MTV awards show. The designers will create five custom-made outfits for Bill, while the rest of the band will don pieces from the designer’s regular collection. As teenage groupies screamed outside the show venue, Bill explained it takes him an hour to get ready in the morning — including that Manga-esque hairstyle. “You’re quick baby, just like us,” quipped Dan Caten.
