White and silver dresses can easily veer into wannabe-bridal territory, but leave it to Blake Lively to pull off this hard look with effortless ease. I spied her outside the David Letterman  show rocking this stunning wrap dress by (surprise) Marchesa and silver heels by (shocker) Louboutin.

Are you planning on spending two hours of your weekend watching her latest flick, Savages? Or is B only queen on the mean streets of the Upper East Side?
