PHOTOS: The Best, Worst And Wackiest Dressed Stars At The 2013 Academy Awards

BEST: Jessica Chastain dropped jaws in a sparkling Armani Prive strapless gown that screamed MOVIE STAR! The Zero Dark Thirty nominee, who described the look as “Happy Birthday, Mr. President,” finished off the look with a coat of red lipstick and blinging Harry Winston vintage jewels.

BEST: Kelly Rowland opted for a more modest look than her sexy Grammy gown, looking statuesque in a sculpted black and white Donna Karan Atelier strapless gown that featured a very Angelina Jolie slit.

WORST: Um, Brandi Glanville, your boobs are about to fall out! The Real Housewives of Beverly Hills star looked desperate for attention in a crazily cleavaged nude gown that she paired with sparkly Christian Louboutin heels.

BEST: Reese Witherspoon flaunted her fabulous post-preggers bod in a bright blue and black Louis Vuitton strapless that her daughter helped her pick out, blinged out in Louis Vuitton jewels as well.

BEST: Quvenzhane Wallis looked adorable to the max, pairing her “sparkly and puffy” Giorgio Armani gown with a puppy purse and Forevermark diamonds.

BEST: Amy Adams went big with her frilly and fem, dove grey Oscar de la Renta strapless gown.

BEST: Octavia Spencer rocked a Tadashi Shoji gown with Lorraine Schwartz bling and Prada heels.

BEST: Kerry Washington grabbed attention in a hotly hued and beautifully jeweled strapless Miu Miu gown paired with a Prada clutch and heels, finishing off thel look with Chopard and Fred Leighton bling.

BEST: Olivia Munn radiated in a red embroidered Marchesa fishtail gown.

BEST: Amanda Seyfried looked extremely elegant in Alexander McQueen.

BEST: Jennifer Lawrence opted for the ultimate Oscar gown with her Dior Haute Couture strapless gown, wearing a necklace draping down her back. Though it was very upside-down-cupcake and she struggled to even walk in it, the Oscar nominee definitely stood out in the crowd. She finished off the look with Brian Atwood heels and Chopard bling.

WORST: Zoe Saldana is one of those stars that always makes us pause when she steps onto the carpet, but her Alexis Mabille gown, that just had too much going on and didn’t really make sense, was simply not a hit for her. She finished off the look with Neil Lane jewels.

BEST: Catherine Zeta-Jones literally looked like a trophy wife in Zuhair Murad, blinged out in Lorraine Schwartz jewels.

BEST: Helen Hunt worked it in an H&M gown that she blinged out with $700,000 worth of jewels.

BEST: Jennifer Hudson looked beautiful in a sparkling blue Roberto Cavalli sleeved gown.

WORST: Was Anne Hathaway nipping out or was it just the structure of her pink Prada gown? Regardless, she could have done better for her big Oscar moment.

BEST: Naomi Watts rocked an edgy, cutout Armani Prive sequined gown.

BEST: Adele looked elegant in Jenny Packham.

BEST: Charlize Theron looked white hot and divine in Christian Dior Haute Couture.

BEST: Jennifer Aniston ravished in a red strapless Valentino gown.

BEST: Nicole Kidman flaunted her flawless figure in a slippery sequined L’Wren Scott gown.

BEST: Sandra Bullock looked elegant in Ellie Saab Haute Couture.

WACKY: Leave it to Helena Bonham Carter to sass things up. Though the goth glam actress didn’t go totally over the top with her black and white Vivienne Westwood, she still managed to leave us speechless.

BEST: Stacy Keibler was George Clooney’s trophy girlfriend, wearing a stunning Naeem Khan gown.

WORST: Was that a black trash bag underneath Melissa McCarthy’s grey gown?

BEST: Halle Berry redeemed herself in a custom Atelier Versace gown, that Donatella designed to give Berry a “Bond girl” look.

BEST: Jennifer Garner magnified in magenta, custom-made Gucci gown, adding jaw-dropping 200 carats of Neil Lane diamonds, worth over $2.5 million and Brian Atwood heels.

BEST: Kristen Stewart kept it tame and in a cream-colored Reem Acra strapless gown.

WORST: Salma Hayek’s Alexander McQueen Gucci gown was dramatic enough that she didn’t need to go so overboard with her updo. She finished off the look with Cindy Chao jewels.

WORST: We don’t usually put a celeb’s mom in a gallery, but Bradley’s mom, Gloria, donned such a distracting outfit we can’t help ourselves. Not only did her pink feathered caplet look awful on the red carpet, but it kept blowing in Jennifer Lawrence’s face during the show.
