Gossip Girl's sixth and final season will premiere on Oct. 8, but we've already spotted the show's stars on the streets of NYC in a bevy of covetable outfits. Blake Lively repped Serena van der Woodsen's signature upscale bohemian vibe in a printed Juicy Couture maxi dress with an equally cool cloche hat one day, and the next, donned the most perfect mix of richly-hued Fall layers. Meanwhile, Leighton Meester's character, Blair Waldorf, put a retro spin on her Upper East Sider wares in a brightly-printed sheath-and-tweed overcoat getup, complete with Valentino bag. New cast member Sofia Black-D'Elia showed off a borrowed-from-the-boys sensibility, Michelle Trachtenberg's villainess, Georgina, took mix-and-match styling to the next level, and let's just say we're totally smitten with an ombré-meets-lace Jenny Packham gown. Here's your first look at what's trending — from the most summery sheer floral maxi skirts to Fall's best boots — on the set of Gossip Girl season six.
