Hey there Upper East Siders!

After a month-and-a-half hiatus, Gossip Girl is back tonight to finish out the last five episodes of its fourth season, and hopefully will answer a slew of unanswered questions: Will Blair and Dan take their affair public? How will Chuck hold onto his beloved Empire Hotel? Will Serena be able to keep Ben...and not mess it up? Will Nate's man bangs return?

Since its premiere in 2007, the teen drama's cast has become known for their fashionista-coveted wardrobes in addition to their roller coaster plot lines. So in honor of the show's return, Us Weekly pulled together Serena and Blair's best style moments to date, from B's polished and preppy cocktail dresses, to S's skin-baring, well, everything.
