The Katy Perry Look Book

Katy Perry shows no fear when it comes to red-carpet dressing. Whether it’s a cupcake bra, a presidential ballot mini, or an LED-powered gown, the pop star’s fashion choices always have some shock value. When she’s not in a costumelike getup, the singer still brings the drama in attention-grabbing designer numbers, like the cleavage-baring Gucci gown she chose for this year’s Grammy Awards and the tiny Dolce & Gabbana crop top she wore at Coachella. See Katy Perry’s style transformation from forties pinup girl to blue-haired couture-wearing star in our ever-expanding new slideshow.
