BEST — Rita Ora, 2015. Singer-actress Rita Ora was praised for this risky dress she wore to the 2015 Oscars. The dark gown was designed by Marchesa.
BEST — Rosamund Pike, 2015. Oscar-nominated for her performance in "Gone Girl," Rosamund Pike also won praise from fashion critics for this dress at the 2015 ceremony. The stunning red gown came from Givenchy Haute Couture.
BEST — Emma Stone, 2015. Showing a lot of leg can be risky (see Angelina Jolie at the 2012 Oscars), but nominee Emma Stone pulled it off with this Elie Saab dress at the 2015 Oscars.
WORST — Gwyneth Paltrow, 2015. Oscar winner Gwyneth Paltrow has had a long history of outstanding fashion moments but this Ralph and Russo gown at the 2015 Academy Awards wasn't deemed one of them. It marked one of the few times fashion critics were left unimpressed by Paltrow.
BEST — Zoe Saldana, 2015. "Star Trek" actress Zoe Saldana stunned on the red carpet at the 2015 Oscars in this Versace gown. Her look was even more impressive upon considering she had given birth to twins just over two months earlier.
WORST — Julia Roberts, 2014. Even Hollywood's most beloved actresses are not safe from the fashion police. Roberts' black Givenchy dress at the 2014 Oscars was criticized for being too dull.
WORST — Liza Minnelli, 2014. Oscar winner Liza Minnelli stole headlines at the 2014 Academy Awards for wearing this blue number. The look was slammed by many fashion critics.
BEST — Lupita Nyong'o, 2014. When Lupita Nyong'o won an Oscar at the 2014 show, her dress nearly stole the headlines. This light blue Prada gown announced Nyong'o as a burgeoning fashion icon.
WORST — Melissa McCarthy, 2013. A year after Melissa McCarthy was nominated for an Oscar, she showed up at the 2013 ceremony in a dress many fashionistas criticized for being too drab. The gown was designed by David Meister.
BEST — Charlize Theron, 2013. The statuesque Charlize Theron stunned fashion watchers at the 2013 Oscars in this white gown from Christian Dior.
WORST — Emma Stone, 2012. Oscar nominee Emma Stone has become a fashion star in recent years but she wasn't given much credit for this dress at the 2012 Academy Awards. The massive bow on her neck stole the headlines. The dress was designed by Giambattista Valli.
WORST — Meryl Streep, 2012. She's been nominated for more Oscars than any actor in history but at the 2012 show, she didn't please many critics. This golden Lanvin gown appeared on many worst-dressed lists.
BEST — Gwyneth Paltrow, 2012. Gwyneth Paltrow's pink dress from the 1999 Oscars is still widely considered her best red carpet moment but this look from the 2012 Oscars also earned praise from fashionistas. The outfit was designed by Tom Ford.
WORST — Anne Hathaway, 2011. Oscar winner Anne Hathaway is known for her chic red carpet style but this 2011 Oscar dress from Valentino was chalked up as a loser by fashion critics.
BEST — Mila Kunis, 2011. In support of her film "Black Swan," actress Mila Kunis topped several best-dressed lists at the 2011 Oscars. The gown was designed by Elie Saab.
WORST — Helena Bonham Carter, 2011. This Oscar-nominated actress has always been a rebel on the red carpet and her look in 2011 was no different. The dress, from designer Coleen Atwood, was not a favorite of fashion critics and her Union Jack garter topped off the unconventional look.
BEST — Jennifer Lawrence, 2011. Jennifer Lawrence's first appearance at the Oscars was a coming-out party of sorts for the young actress. Her red Calvin Klein dress scored with fashion critics even though she didn't win an Oscar that night.
WORST — Charlize Theron, 2010. Oscar winner Charlize Theron was called a fashion loser after wearing this Christian Dior dress to the 2010 show. Not surprisingly, the two conspicuously placed flower designs were picked on most.
WORST — Georgina Chapman, 2010. Actress Georgina Chapman is also a fashion designer by trade, which made her 2010 Oscar dress such a shocker for fashion critics, who panned the dress.
BEST — Marion Cotillard, 2008. The French actress looked gorgeous in this Jean Paul Gaultier dress at the 2008 Academy Awards. Her winning look was fitting as she would win an Oscar for her work in "La Vie en Rose" at the show.
WORST — Vera Farmiga, 2010. Vera Farmiga's performance in "Up in the Air" earned her an Oscar nomination, but her dress at the 2010 Oscars earned a resounding "thumbs down." Farmiga's gown was designed by Marchesa.
BEST — Sandra Bullock, 2010. On the night Sandra Bullock won an Oscar for her performance in "The Blind Side," she also was named one of the best-dressed stars at the show. This Marchesa gown was immediately hailed as a classic Oscar dress.
WORST — Whoopi Goldberg, 2009. Oscar-winning actress Whoopi Goldberg took heat from fashion critics when she showed up at the 2009 Oscars in a leopard-print dress designed by Christian Dior.
WORST — Marion Cotillard, 2009. This Oscar-winning actress is normally a darling of best-dressed lists during awards season but not in 2009. This Christian Dior dress drew ire from fashion critics.
BEST — Anne Hathaway, 2009. The year Anne Hathaway was nominated for her first Oscar, she floored fashion critics with her Armani Prive gown.
WORST — Beyoncé, 2009. Her name doesn't often appear on any lists with the word "worst" attached but Beyoncé's 2009 Oscar dress left many fashion critics scratching their heads. The gown was from House of Dereon Couture.
BEST — Amy Adams, 2008. Five-time Oscar nominee Amy Adams stunned in this green dress at the 2008 Oscars. The gown was designed by Proenza Schouler.
WORST — Tilda Swinton, 2008. Oscar winner Tilda Swinton is one of Hollywood's most fashion-forward stars but this Lanvin dress at the 2008 Oscars didn't earn kudos from fashion critics.
BEST — Nicole Kidman, 2007. Oscar winner Nicole Kidman showed off her trademark elegance with this red Balenciaga dress at the 2007 Academy Awards.
BEST — Penélope Cruz, 2007. Beloved Spanish actress Penélope Cruz didn't win an Oscar in 2007 but she may have won the "best-dressed" honor at the show. Her Atelier Versace gown stunned the fashion police.
WORST — Charlize Theron, 2006. When Charlize Theron was nominated for her second Oscar in 2006, she wore this green Christian Dior gown to the ceremony. The look was widely panned by fashion critics, who said the gorgeous star seemed to get lost in its grand design.
BEST — Keira Knightley, 2006. This look from nominee Keira Knightley at the 2006 Oscars has since become iconic. The dress was later named as one of the ten greatest red carpet gowns of all time by Britain's "The Daily Telegraph." It was designed by Vera Wang.
