Ahead of the 84th Annual Academy Awards, we're casting our minds over Oscar gowns past.

In 2011, Michelle Williams gleamed in Chanel couture, while Mila Kunis looked pretty perfect in a lavender Elie Saab couture creation. Every year yields its iconic looks, sure to be remembered and referenced on red carpets to come. Ahead of our Oscars coverage, we’ve put together the ultimate Oscars retrospective of some looks you're bound to remember, and others you don’t.

From a tearful Gwyneth Paltrow in pink Ralph Lauren in ’99 (was it really that long ago?) to Audrey Hepburn picking up Best Actress for Roman Holiday in ’54, plus that naughty duo Pam and Liz in 2001, take a journey back through the history of the Oscars red carpet.

Need a reminder of all of last year's best looks? Find our full 2011 Academy Awards red-carpet rundown here. And see our predictions for which actress will wear which couture gown.

We'll be live-tweeting the Oscars @ELLEUK and bringing you all the news and red-carpet galleries first thing on Monday morning. Register to receive our Oscar newsletter here.
