Oscars 2008

The sexy Dior tuxedo that Sharon Stone wore to Elton John's party was not only fashionable, but totally functional. "I'm all about comfort, and this is so comfortable. It's like wearing pajamas," said the actress. "I can dance, eat, breathe." Stone—who watched the Oscar broadcast with fellow guests Josh Groban, Ellen DeGeneres and Portia de Rossi(in Lanvin)—was also able to host one of her infamous auctions to raise funds for AIDS research.
