Sir Elton John held his annual White Tie and Tiara Ball last night in Windsor, England. And what's a girl to wear to the esteemed event, which raised millions of dollars for Elton John's AIDS foundation? Well if you're Lady Gaga, who also performed at Elton John's ball, you wear a pearl-covered Latex Francesco Scognamiglio see-through dress with strategic cutouts at your "Woohoo," plus a white lace bra and undies (for good measure), an amazing blonde bouffant and a bejeweled Viktor & Rolf catcher's mask. Plus white, sky-high custom-made heels by Noritaka Tatehana, the same designer who made her footwear in the "Alejandro" video. But that's all probably just obvious at this point, is it not?
