Over the course of the 19th century, American weddings gradually transformed from private, informal celebrations to elaborate and expensive spectacles. In mid-19th century New York City, many marriages took place at home. The reenactment of the 1845 wedding of Elizabeth, the oldest daughter of Seabury and Eliza Tredwell, is based on extensive research about 19th century ​weddings, as well as information in the museum’s archives. The museum’s blog takes an in-depth look at the weddings customs of the period.

This special event is the centerpiece of the museum’s current exhibition, Tredwell Brides: Changing Wedding Traditions in the 19th Century,which explores the changes in wedding customs as the 19th century progressed, including the trousseau, printed invitations, and the giving of gifts. Highlights include Eliza Tredwell’s 1820 empire-style embroidered cotton wedding dress and Sarah Ann Tredwell’s 1872 silk bridal dress made in Paris, the highest fashion of the post-Civil War bustle period. Accessories include silk wedding boots, and earrings, corsage, and headpiece of wax orange blossoms. The exhibit is free with museum admission. Guests to “Dearly Beloved” may tour the exhibition at 6 p.m. before the ceremony.
