Britney Spears kicked off her Femme Fatale tour last week with a glittery new stage wardrobe, and we scored the details on what made them shine: Swarovski crystals! For Britney's opening look, her costume designer Zaldy Goco sewed clear crystals onto a white leotard for a shimmery disco ball effect. Later in the show, Brit plays Cleopatra in mirrored gold bikinis, amps up the sparkle in beaded latex and goes digital in costumes encrusted with LED lights!
