Let's be honest: we all remember Britney Spears and Justin Timberlake's matching denim ensembles from the 2001 American Music Awards.
While the outfit may not be the most stylish for obvious reasons, the look reignited the denim trend and undoubtedly had fans buzzing for years (even Katy Perry wore a similar tribute dress to the 2014 MTV VMAs).
When it comes to memorable red carpet moments, Britney, Justin and their denim duds are of course at the top of our list, but what about the other notable fashions?
From Lupita Nyong'o's red Ralph Lauren cape-gown which she rocked at the 2014 Golden Globes and cemented her status as a style star to Gwyneth Paltrow's pretty pink confection she wore to the 1999 Academy Awards, there's no question that the perfect dress can quickly elevate a celebrity's status.
But of course, along with the good, we're also taking a look at the bad (Bjork's swan dress, anyone?).
