The end is nearly here! After six seasons on the CW, Gossip Girl's final episode (a two-hour affair) airs tonight, starting at 8 p.m. EST. From the very beginning, we fell in love with the show's salacious Upper East Siders, including All-American girl Blake Lively (aka Serena van der Woodsen). She lights up the screen whenever she's on it—and she has the same effect on the red carpet in whatever she wears, like Lanvin, Gucci, Isabel Marant, or Chanel (shown above, from left to right). Click through the gallery to see all of Blake's best looks ever, and check out all of her stylish glory in our new Look of the Day grid!
