Noooo.... I was typing too fast, hit something, and lost my earlier reply... here is the re-type....
VW #1 is very you - cool, unusual, can stand on its own, and yet is enough of a blank canvas that you can wear it again and again, and accessorize it in any style direction you want, and it will look like a different dress every time. Not a one-hit wonder to hang, unworn, in a closet. This dress gets my vote, unless you already have a similar dress that serves the same, chameleon-function.
I reallyreallyreallyreallyreally love the Stella McCartney! Can you justify the expense by wearing it to the opera as well? Holiday parties?
I love the Raoul too, it just says 'summer' to me. How is August in your neck of the woods? Still warm enough to support this dress? It looks kind of thin.
VW #2, I like this as well, but the neckline is kind of bland to me. But the waist and the skirt make up for it.
I like the Kay Unger, but there seems to be something missing or lacking with it. It doesn't seem Anna-worthy. You set a high style bar, and I don't know if this dress quite meets it. I'd be curious to see it on you.
The Cadeymint: I start out loving this dress, because the stripes are so lovely, and the colors, and I love the neckline and the bodice... then my eye gets pulled away, down to that hemline, and I feel all sad. The hemline upstages the rest of the dress, and it pulls my eye away from the model's face. IMO.
Carmen Marc Valvo & the RED Valentino, I feel are just 'meh'. Bridesmaid-y.
