Blake Lively attended the premiere of new movie Twelve last night in New York. As one would expect the premiere also attracted a collection of Gossip Girl co-stars including Chace Crawford (who stars in the film), Anna Trachtenberg and Jessica Szhor. In the style stakes Blake can be a little generic but last night the actress pulled out all the stops.

For the event Blake chose a stunning mini dress from the resort collection at Chanel pictured above. We will always love a shift dress but this one is particularly exquisite, the combination of navy with the mesh panel around the middle and backless detailing are fabulous! Blake teamed the look with nude Christian Louboutin slingbacks.
