Happy birthday, Madge! Though it may be hard to believe, the Queen of Pop turns 55 today. While we’d love to be part of the birthday festivities that almost surely include a ton of shirtless men and a sea-vegetable cake, what could you possibly get a woman who has a billion dollars, the arms of a warrior goddess, and a wardrobe full of hip-bone-baring leotards? Nothing. So instead, celebrate by slipping into your favorite cone bra and taking a look back at some of the birthday girl’s best fashion moments.
