A few costumes from the 1860s Fancy Dress Ball hosted by the Lancaster Civil War Explorer Post.
Above: A few of the Three Graces, Zeus, and a Regency Dress (worn by Jenna Baumgartle from thesewingacademy.org).
My good friends Jim and Eileen Bish wearing their masks. Eileen's mask is a Black Cat, and Jim is the Midnight Sky. 1860s masks often had curtains on them light this.
