Jessica Chastain in Alexander McQueen: This gorgeously embroidered gown made many best-dressed lists, and it's easy to see why. It was a refreshing departure from the more typically over-the-top red carpet gowns, and her overall look was completely effortless and beautiful.
Gwyneth Paltrow in Tom Ford: Refinery29 recently ran an article discussing the problem with a lack of personal style on the red carpet, but I think that Gwyneth embodies her own sense of fashion at every event. Case in point: This structurally sleek gown (plus cape!) is a look that only a modern maven like Gwyneth could pull off so perfectly.
Rooney Mara in Givenchy: I loved seeing Rooney stray from her safe spot of all-black gowns and go for this more feminine option. The back was incredible!
Ellie Kemper in Armani Prive: I didn't see this much color variation when watching the red carpet footage, but on-screen this sleek sequined gown was simply stunning. I love the way the rusty shade plays off her hair color - but as a redhead myself, I may be a bit biased!
Tina Fey in Carolina Herrera: I am always surprised by simplicity, and this navy blue frock was gorgeous on Tina. She was able to look simultaneously classy and trendy (peplums as a major trend this spring).
Angelina Jolie in Atelier Versace: Did she look incredible? Yes. A little too thin? Of course. But my real problem with her was the completely ridiculous stance she made in order to stick her leg out of this slit in this otherwise perfect gown. Apparently, I'm not the only one who found this appaling - her behavior spawned a Twitter feed for her right leg and a new internet craze called "leg-bombing."
Cameron Diaz in Gucci: I don't know why she was at the Oscars in the first place, but you wouldn't have known based on this boring pick with a fairly questionable jagged hemline.
Melissa Mccarthy in Marina Rinaldi: The color is alright, but overall this choice wasn't flattering on Melissa at all - the strange sleeves made her look far wider than she is.
Sandra Bullock in Marchesa: It kills me to put a Marchesa dress on this list, but this is a case that's all about the fit. If the top had just been more fitted, I really think this could have been a winner. Instead, it made her torso look like a rectangle.
Shailene Woodley in Valentino Couture: This matronly dress was just a total miss for me. Shailene would have done better to follow the lead of last year's up-and-coming young actress, Jennifer Lawrence, and stuck with something a little more age-appropriate.
