For the season finale of American Idol on Wednesday, judge Jennifer Lopez sizzled in a shimmering long-sleeved mini by designer Kaufmanfranco that was accented by tousled, va-va-voom hair and glowing makeup. The result? A spectacular fashion moment that, quite frankly, is inspiring us to hit the gym (have you seen those legs?). "Tonight was the finale so we wanted something special," stylist Rob Zangardi exclusively tells InStyle of her ensemble. "We chose this metallic mini dress that sparkled on stage and paired it matching sparkly shoes." Want more J. Lo fashion?
