Cass Balzer writes: “On a leisurely Saturday afternoon, guests draped in Regency-era fashion—lightweight muslin and chiffon, adorned with delicate lace and ribbons—converge in an airy hall to indulge in a spread of tea, elaborate pastries, cakes crowned with sugared berries, and delicate canapés. But this isn’t 19th-century London. It’s the 21st century, these guests are gathered at Collier County (Fla.) Public Library. Amid a resurgent interest in TV period dramas, public libraries are hosting Regency- and Victorian-era-themed programs featuring book discussions, trivia, crafts, and, of course, tea.”
