The dresses, which have an asymmetric neckline and puffball skirt in the shape of rose petals, were made in purple, grey and lavender among other colours. Blair\'s BFF and maid of honor, Serena van der Woodsen (Blake Lively), will be decked out in Vera Wang\'s \"Farrah\" gown, a long organza and metallic tulle gown with a corset bodice and blossom flange skirt, straight from the designer\'s spring 2011 wedding collection.
