I'm not used to seeing Serena so conservative on Gossip Girl, but I think I like it. In this scene, the hottie donned a Mason by Michelle Mason Mocha Shirtdress ($425). The warm hue looks amazing against her blond locks, and I love the unique zipper detail. A cool twist on a timeless shape.

BTW, if there's any top, dress, shoe, or bag you're dying to identify, join our In Search Of . . . Fab Community group, and we'll help you find that coveted item!
