Spotted: Gossip Girl's Blair and Serena (Leighton Meester and Blake Lively) strolling through Columbia University's campus in super-bright colors-that are Fall-tastic! We especially love Serena's Madison Marcus buttoned down yellow vest and D&G pinstripe shorts which are perfectly accessorized with a Fallon Veruca chain bib necklace, an Alexis bittar cuff and a bright-blue Mulberry Leah Hobo. And not to be over-looked is Blair's super-flirty and fun printed Nanette Lepore dress which she pairs with nude heels and a stunning Nancy Gonzalez bag. Swoon! Super-excited for tons of fashion on the new season which starts Sept. 13th on the CW.
