Charity Ball 2011 - What to wear?

I need your help! I have 100 dresses in my closet and "nothing to wear"! So, I've decided to rent from renttherunway.com. These 2 dresses are on the way to my house and I'm crossing my fingers that one of them works. Please leave comments and let me know what you think. Wiley wanted to know, "where's the other shoulder?". lol
