For those who might not remember -- Katy and Riff Raff replicated Justin Timberlake and Britney Spears' iconic matching denim outfits from the 2001 American Music Awards. It has gone down in history as one of the most tragic wardrobe choices of all time -- but it was the early 2000s so we've learned to forgive.
We have to thank Katy and Riff Raff for bringing it back though and bringing that level of awful to a whole new generation of watchers. Cheers, Katy.
