Gone are the days where Bill Clinton's former mistress wears oversized shirts. Monica Lewinsky wowed at the Vanity Fair Oscar After-party in a classic black ball gown.

Lewinsky is now a powerful figure in the anti-bullying realm, using her own personal experience to empower others. The 42-year-old recently spoke at a TED talk last year about what it was like to be shamed on a worldwide scale and how she fought back to reclaim her narrative.

"I was Patient Zero of losing a personal reputation on a global scale almost instantaneously," Lewinsky said. "I was branded as a tramp, tart, slut, whore, bimbo and, of course, 'that woman.' I was known by many, but actually known by few. I get it. It was easy to forget 'that woman' was dimensional and had a soul."
