Fortunate dinner guest (and Tripp's wife) Maureen Vanderbilt dresses up for the van der Woodsen Thanksgiving in an Oscar de la Renta floral dress (shown here in another color combination). She wears it well with black opaque tights, an embellished cardigan, and two-toned pumps, giving little Serena a run for her money. Although her look isn't quite as provocative, it's just as eye-catching. Shop it all now!
