One will be Emma Watson in my earlier post. Love that dress. I really think she's been coming into her own recently and really showing a more grown-up fashion taste. I remember the first Harry Potter where she's just a skinny kid with huge hair. Then a few years later chatting online with a friend and he says "Jennifer Aniston is looking hot on Jay Leno". I change the channel and the girl is decked out in all black, hair Jennifer Aniston Dark Blonde and stick straight. She turns her head and its Emma Watson.
Two is Blake Lively in Dolce and Gabbana at the Sherlock Holmes Premiere.
Wow. Ok I love the dress. Could I ever possibly wear it - since I'm not 6 ft tall and 90 lbs and all legs, no. But if I looked like Blake - in a second. The shoes rock too - sparkly and they look gold but hard to tell in the photo.

Serena (aka Blake Lively) in Tory Burch. The dress is ok but I don't think its a knockout or anything we haven't seen before. It's a gold sequin dress... yawn for pick 2.
Anne Hathaway in Atelier Versace. Again not a fan. I guess it's daring and different but I don't love the color on her or the style.
Cate Blanchett in Valentino. I'm not a huge yellow person but this dress is amazing. Agree 100% she looks awesome and the dress is a knockout. 
Lady Gaga just bothers me. Ok so she's inventive (I guess that's what you call it) but to me a knockout dress is something that other women would want to wear. There is nothing about this outfit that makes me want to wear it. Half of her get-ups make her look totally ridiculous and the other half are completely unwearable. 
I'm more of a Charlotte fan myself but this Versace dress Carrie (aka Sarah Jessica Parker) wore is gorgeous. The tutu, the color, the sparkle. Perfection.
Emma Watson in Ossie Clark. Could I please raid her closet for a day? I love this dress. I would wear this dress everywhere and not even care that its too dressy for 99.9% of the things I go to.
I love Reese and this Nina Ricci dress is simple, almost wouldn't call it a knockout but her whole look is good. I like the red shoes as a nice and unexpected contrast. I think this really shows Reese coming into her own.
