Fabulously Spotted: The “Gossip Girl” actress Michelle Trachtenberg stepped out for the 2012 opera season opening of “L’Elisir D’Amore” in New York City looking stunning! She wore a gorgeous blue Notte by Marchesa gown with taffeta bodice, accessorized with a statement necklace and carried a bejewelled Fall 2012 Marchesa clutch. Making her look absolutely flawless is her slicked back ponytail, smokey eyes and nude lips. Perfecto!!
