Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/cameron-diaz/195733/main' target='_blank'>Cameron Diaz</a>

Cameron Diaz looks washed out and overwhelmed in a complicated Dior gown (and way too uncomplicated hair and make-up). Next time, just keep it simple, Cam.

<a href='http://movies.aol.com/celebrity/marion-cotillard/195575/main' target='_blank'>Marion Cotillard</a>

Sushi, anyone? French star Marion Cotillard usually has us seeing through <a href='http://movies.aol.com/movie/la-vie-en-rose/26837/main' target='_blank'>'Rose'</a>-colored glasses, but this fish-y Jean Paul Gaultier look is just a big flop.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/miley-cyrus/474330/main' target='_blank'>Miley Cyrus</a>

Red may be the color of the night, but it&#39;s not easy to pull off. Witness Miley Cyrus in a cap-sleeved Valentino gown and bright lipstick. She just looks a little too styled for her 15 years. Maybe if she&#39;d come as Hannah Montana

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/amy-adams/273224/main' target='_blank'>Amy Adams</a>

Amy Adams' stunning Proenza Schouler ensemble would be amazing in just about any shade -- except this one. The blah hunter green is frighteningly reminiscent of a Gap rugby shirt, circa 1992.

Oscars Worst Dressed 2008

Sarah Larson

George Clooney's gal pal Sarah Larson disappoints in a pastel strapless Valentino that reeks of grandma&#39;s old curtains. At least she went easy on accessories -- she already has the best one on her arm, after all.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/tilda-swinton/69397/main' target='_blank'>Tilda Swinton</a>

Anybody else completely baffled by this one-sleeved silky Lanvin number? The only explanation we can come up with is that Tilda Swinton is channeling <a href='http://movies.aol.com/celebrity/david-bowie/82636/main' target='_blank'>David Bowie's</a> look from <a href='http://movies.aol.com/movie/the-man-who-fell-to-earth/1022095/main' target='_blank'>'The Man Who Fell to Earth.'</a>

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/hilary-swank/167442/main' target='_blank'>Hilary Swank</a>

Note to Hilary Swank: Versace just isn't your friend. The flowers, the sheerness, the layers, the criss-crossing this uber-busy gown overshadows your petite frame instead of flattering.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/daniel-day-lewis/17559/main' target='_blank'>Daniel Day-Lewis</a>

We don't care if he's the awards favorite, we just can't drink this milk shakin' mess. Daniel Day-Lewis leaves blood on the red carpet, in the form of a brown-trimmed tux and hoop earrings.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/helen-mirren/49576/main' target='_blank'>Helen Mirren</a>

Usually the pinnacle of red carpet chic, Helen Mirren gives fans the cold, Swarovski-encrusted shoulder in this Georges Chakra gown. Snip those sleeves, then the Queen will reign again.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/cate-blanchett/215038/main' target='_blank'>Cate Blanchett</a>

Oh mama! Normally a regal presence at awards shows, Cate Blanchett inspires little more than a "huh?" in this Dries Van Noten purple ensemble. It can't be easy dressing a bump, but a longer hemline would be a good start.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/viggo-mortensen/50903/main' target='_blank'>Viggo Mortensen</a>

Viggo Mortensen&#39;s subtle striped tie and throwback boutonniere were promising until he added that crazy-long coat. Men also need to heed Coco Chanel&#39;s advice: Sometimes too many accessories are just too many.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/kelly-preston/57732/main' target='_blank'>Kelly Preston</a>

Following the unacceptable trend of too-short dresses, Kelly Preston's saffron-hued Roberto Cavalli gown leaves us wanting more ... fabric, that is.

Oscars Worst Dressed 2008

<a href='http://movies.aol.com/celebrity/nicole-kidman/38065/main' target='_blank'>Nicole Kidman</a>

Why in the world would pregnant Nicole Kidman choose to cover up naturally-boosted assets with strands of tinsel? Sure, her simple Balenciaga gown needs a sparkly boost, but maybe a different dress would&#39;ve been a better answer.
