The surprisingly long-lasting PR machine/pop star that is Lady Gaga was surprisingly quiet – that is, her wardrobe at least – for her performance at the Met Costume Institute Gala this past Monday. But come tonight, Gaga has a much bigger stage for her choreographed singing and dancing. The pop star knowing for using soda cans as rollers is slated to appear on American Idol tonight. And in typical eye-catching form – even though moderated just a tad for primetime TV – Gaga is slated to wear an Armani silk mesh bodysuit with embroidered Chantilly lace and crystal and jet beading. Over it, she will wear a silk organza cape with an embroidered hood and black patent stiletto boots. Somehow, we’re guessing the jet beading is going to be strategically placed. The designer chatted on the ongoing design collaboration. “American Idol is a real modern phenomenon that has captured the public’s imagination and delivers great drama,” said Giorgio Armani.
