The first dress is a Kate Moss maxi ruffled dress (ss09) for topshop. She wore this dress twice: in the first picture she's paring it with a fushia Sondra Roberts clutch, in the second picture she goes for a more soft look and let her boyfriend do the rest. ;-)
The second dress is Diane Von Furstenberg. Is it just me, or do Johannes and Olivia's outfits color-match perfectly everytime?
The last dress is a dramatic Valentino gown. I love how she pairs it with a red clutch and that her hair is loose. To me she looks like a modern greek goddess!
Let me know what your favorite dress is!
