The Phillips Collection held its classy and splashy gala May 16 at the Dupont Circle landmark for its show, “Made in the USA: American Masters from the Phillips Collection, 1850-1970,” and to recall the vision of its founder, Duncan Phillips. After dinner amid the artwork and a slew of art lovers, influencers, politicians and business persons, the after party moved to Anderson House for all to let their hair down. The gala raised more than $750,000 for the art gallery.
