WE SEE THAT since March 1 the aristocrats of Downton Abbey have been facing off against their American counterparts in a fashion exhibit at Winterthur, the Delaware estate of Henry Francis du Pont. Forty costumes from the PBS series, plus antiques and accessories, are being shown at Winterthur’s museum, joined by similar items from the du Pont collection. A timed ticket will be required to view the post-Edwardian frocks and country-gentleman attire, but you have till January 4, 2015 to make the trip. Visitors can also make arrangements to attend brunch or afternoon tea. And those who are truly carried away can buy things such as the white cotton-knit tea gloves that Lady Mary wore to Lady Edith’s wedding, in the museum’s Downton Abbey store.
