Best/Worst Red Carpet Style of '13

Johansson was simply stunning in a black off-the-shoulder Versace gown, which she accessorized with a pink and blue sapphire, emerald, and diamond necklace from the Bulgari High Jewelry collection.

The fashion press compared the mommy-to-be's in Givenchy by Riccardo Tisci floral print gloved gown to everything from a chintz sofa to bad wallpaper, but it was Robin Williams who delivered the ultimate sartorial zinger.

It was bad enough that we could see Paltrow's side butt through the sheer panels in her Antonio Berardi gown, but did we really need to know that she had to shave her bikini line before she put it on? TMI, Gwyneth!

Though Vergara's cleavage-baring crimson gown by Vera Wang drew mixed reviews, it was unquestionably the sexiest dress of the night.

Hudson's dramatic Alexander McQueen gown was the perfect mix of Victorian and vixen. The keyhole cut-out is not an easy look to pull off, just ask Katy Perry.

This harlequin print and lace jumpsuit by Balmain was a fashion risk that wasn't worth taking, but at least Miley was wearing pants.

She wasn't a nominee, but with that white Dior Haute Couture bustier dress, those Harry Winston diamonds, and her post-movie pixie hair, Theron was the best dressed actress at the Oscars.

The CBS standards and practices department — which issued a wardrobe advisory warning performers, presenters, and audience members against over-exposing themselves — may deserve partial credit for Rihanna's unbelievably chic and appropriately covered-up look; a candy-apple red custom Azzedine Alaia gown with matching red lips and nails, and soft, romantic wavy hair.

Wearing a leopard-print dress by Emanuel Ungaro, Perry was one of the night's best dressed stars?until she opened her mouth. Let's all pray that lady grills are one celebrity fashion trend that will end along with 2013.

The bib-like neckline of her Prabal Gurung dress had me wondering if Jones had stopped off at Red Lobster on her way to the SAG Awards, and I couldn't even imagine an explanation for the pompadour hairstyle and orange lipstick. What happened to this January Jones?
