Fashion Flashback! The Best Worst & Wackiest Fashions Of The Academy Awards

The biggest red carpet event of the year is almost here!

From swan gowns and sheer disasters to the most beautiful and intricately designed dresses we have ever seen, we have several wardrobe winners and at the Oscars over the years. In honor of the 2013 Academy Awards on Sunday, RadarOnline.com is taking you on a walk down red carpet memory lane with photos of the best, worst & wackiest dressed stars is the history of the show.

Cameron Diaz is a blonde bombshell with one of the hottest bodies in Hollywood, so when she showed up on the red carpet in 2010 wearing an impeccably embellished Oscar de la Renta gown fit for a princess, all eyes were on her.

And who can forget Michelle Williams  spiking the mustard yellow trend back in 2006, when she radiated in one of Vera Wang's wondrous creations?

Academy Award winning actress Hilary Swank  has landed on both the best and worst dressed lists over the years. In 2000, she claimed victory in her olive green Randolph Duke, but three years later, flopped on the carpet in a Christian Dior ensemble, which featured a sheer overlay of pink tulle.

Reese Witherspoon  usually plays it safe in timeless and tasteful couture, but slipped up in 2009 in an over-the-top, blue and black Rodarte gown.

From Bjork's  infamous Marjan Pejoski swan dress and Demi Moore's  1986 BMX babe meets medieval times ensemble, sometimes the biggest of fashion flops can be the most entertaining.

Another famous red carpet flub? Uma Thurman's  Swiss Miss Christian Lacroix gown in 2004.
