"I always think about wearing something a fan could buy and make her own," Beyoncé told W earlier this year. "As a young girl I remember seeing so many artists, and then I’d try to dress like them. I sewed zippers on my jackets to be like Michael Jackson." The video for "Countdown," the overwhelmingly energetic new single from 4, is further evidence of this philosophy, with the R&B icon sporting a variety of dazzling looks that could definitely be emulated by fans on the cheap. The clip is nearly as joyful and super-charged as the song itself, with its barrage of world-class hooks complemented by a rapid succession of memorable, charming and sexy images.
