Michelle Williams looks adorable in coral peplum Louis Vuitton. The strapless gown fit her delicate figure perfectly, and the “My Week With Marilyn” star kept it simple with a single strand of diamonds and a Mia Farrow-like haircut. | AP

“Bridesmaids” star Kristen Wiig chose nude-toned J. Mendel for her big moment, and its ethereal floatiness make it a winner. Her tousled hair is a bit too casual, though, for the red carpet. | Getty

Sandra Bullock’s black-and-white dress by Marchesa will be fiercely debated by fashionistas. It’s almost there, but it comes down to the fit, which is blowsy on top, and doesn’t hang quite right. | Getty

Gwyneth Paltrow wasn’t nominated for an award this year, but if awards were given out for best-dressed, she’d be nominated for the perfection of the caped, long white dress by Tom Ford accented by her deep tan. | Getty

Brad Pitt and Angelina Jolie were the most beautiful couple on the red carpet, per usual. The point of Jolie’s black Atelier Versace gown was the thigh-high slit, from which she awkwardly thrust her leg out for photos in every single shot. | Getty

Rooney Mara opted out of her normal black for ivory, but her pale skin doesn’t work with this Givenchy gown, and the severe bangs and red lips give too much edge. | Getty

“The Descendants” star Shailene Woodley, 20, chose vintage Valentino from the ’60s, but its silhouette suggests it was made to be worn by woman in her 60s. | Getty

Radiant Emma Stone just misses in this fuchsia frock by Giambattista Valli because the neck bow is as big as her head. | Getty

George Clooney is dashing, and girlfriend Stacy Keibler is stunning in a rose gold Marchesa gown plucked straight from the runway. | Getty
