The Fair of Peace and Fraternity of the Free World (Feria de la Paz y Confraternidad del Mundo Libre) was an international world's fair that took place during the Trujillo Era in Santo Domingo, Dominican Republic (then called Ciudad Trujillo) in 1955–56.

Accompanied by 150 "princesses" she wore a white satin dress bordered with 600 Russian ermine furs and a 75 feet train that had been commissioned for $80,000 at Fontana from Rome.
