Remember when Gillian Anderson wore this exposed thong on Oscars night?

The scene: The year was 2001 at the Academy Awards. Julia Roberts won Best Actress for her role as Erin Brockovich and celebrated with then-boyfriend Benjamin Bratt. "Gladiator," "Traffic" and "Crouching Tiger, Hidden Dragon" picked up multiple awards throughout the night. Björk, infamously, wore a dress with a white swan looped around her neck.
