From March 1st, 2014 through January 4th, 2015, Winterthur will be staging an exhibition of 35 costumes from Downton Abbey! According to the press release, the exhibit will also include "photographs and vignettes inspired by the fictional program and by real life at Winterthur." Winterthur, a 175-room mansion, was completed in 1932 as the home of the Du Pont family and is the fifth-largest historic house in the country. Now a museum of decorative arts, it features both its original period rooms and gallery space to display over 90,000 objects produced or used in the United States between 1690 and 1860.
I sense a road trip approaching... :-)
