First, the WORST. Really though, they were just mis-steps and not horribly tragic. Tilda Swinton. I applaud her no-makeup and statuesque stance and I actually like her outfit, but not on her. The top is nearly the same color as her skin so the draping cannot be appreciated nor can the person wearing it. Her strong lips go a long way to improving the situation but can't compete with a sea of beige.
Miley Cyrus. Maybe she's going after a serious role or wants to start changing her image, but she was dressed like someone in their 40s not teens. Teen years should be fun and experimental and colorful (within tasteful bounds, sure) not matronly. This outfit has no verve.
Evan Rachel Wood. Same problem as Tilda--the beigey-cream color nearly matches her skin so she's overall unimpressive, even with coppery hair, dark nails and lipstick--it can't warm this up enough to do her justice.

Amy Adams and the red dress. It's actually an alright ensemble except for the cloggy shoes! They are too bold and clunky. A simpler shoe would allow the eye to linger longer on that spectacular necklace instead of tripping up on her shoes.
Now, the BEST. While I would have liked to of seen Kate Winslet with softer hair (like Meryl Streep's) to balance the color, sheen and construction of her dress she did master the one-shoulder glamour with a dash of vintage perfection nicely. The one shoulder dress is not one of my favorite looks but it sure is popular again. Her

simple jewelry, the perfect draping of the dress and elegantly natural makeup completed a classy and modern look that fit her stature beautifully.
Ah, Marisa Tomei. She looked elegant and vintage and stunning. That is not an easy color, shape or length to wear. She wore it well. She wore it so well that she's in my top picks, however, it is a bit wedding-dress like which I thought was kind of odd. She probably knew that and still chose it, gutsy.
Meryl Streep looked amazing. The taupe tones in the dress matched those in her skin and hair and the effect was simply divine. Her soft, natural makeup and hair added a youthful, fresh finish to a lovely ensemble. She was the perfect example of "Wear it Like You Mean It" because without her grace and confidence, the dress could have been dull.

Let's focus on orange. I love this color on the red carpet. It's current and worn exceptionally well by these two ladies, one of whom wasn't listed on Style.com. She's Sir Ben Kingley's wife, Daniela Barbosa de Carneiro. The soft ruffles and shoulder ornamentation fit her figure beautifully while her laid back hair and makeup suited her to stunning effect.
As far as makeup goes--it was all about the lip. Soft, beachy hair and glossed hair and then a naturally vibrant lip. This can be achieved by doing something just a few shades brighter than your normal go-to. Of all the ladies there, Diane Lane was pitch perfect in this arena.
