Bjork has always been quirky with her music, but her fashion sense at the 2001 Oscars was more ugly duckling than beautiful swan.

The infamous "dead swan" dress was so weird that we wouldn't have been shocked if the vigilant folks at PETA called for a cease-and-desist. Hell, they may have even asked her to wear mink instead of this frock.

While it was a fail at the Oscars, it's gone on to have an endless life as inspiration for countless Halloween costumes and has been mocked in movies and on TV shows (including the 2001 Emmys, where host Ellen DeGeneres put her own spin on it).
