No one on Sunday night's carpet was a definite "don't" but there were certainly some misses.
Best Actress nominee Melissa McCarthy disappointed in a pale, gathered gown with an unflattering, flowy sleeve detail. But her nod to childhood friend and shoe designer Brian Atwood on the red carpet was charming (though I'd have liked to see her shoes.) Something more fitted could have been more flattering.
Berenice Bejo's long-sleeved, pale green Elie Saab gown was too matronly, and aged her beyond her years. And the stylists didn't like Penelope Cruz, in Armani Prive, because they thought it aged her. They thought the same of Sandra Bullock's black and white Marchesa.
And the two more mature actresses nominated for Best Actress - Glenn Close and Meryl Streep - were both fashion don'ts. Close's deep green Zac Posen gown topped with a matching tuxedo jacket seemed to be wearing her, and Streep's gold gathered dress by Lanvin added unnecessary bulk to her figure.
"I adore Meryl," local stylist Cora Rasp said, "But her dress seemed outdated."
But Rasp and Sarah Lorsung Tvrdik, another local stylist, had a few better things to say about Meryl Streep's blazer, which they thought was a risk that paid off. They called her their favorite of the mature actresses.
Emma Stone's red dress with a big bow at the neck, designed by Giambattista Valli Haute Couture, was another miss for Lorsung Tvrdik and Rasp.
"The bow should have been more defined and stiff, and the neckline was too bunchy," Lorsung Tvrdik said.
Kelly Osborne, who co-hosted the E! coverage before the show, is going to have to lose her mauve-tinted hair before we take her fashion commentary seriously.
But the worst moment by far: Sascha Baron Cohen as "The Dictator" flanked by two botoxed babes. (Though he did redeem himself a bit by dumping an urn of powder on the otherwise unflappable Ryan Seacrest.)
