Net-A-Porter stocks the crème de la crème of designer fashions from around the world. If that weren't enough, my favorite shopping site has teamed up with London label Preen to house its exclusive 2009 Cruise collection. The line includes the popular hot pink Power Dress — you all loved Gwyneth Paltrow in the black version — along with five additional sexy, modern frocks. If any of these creations tickle your fancy, I suggest you get a move on it. The exclusive collection launches today at Net-A-Porter.com.
