Gladys Zender of Peru won the competition, becoming the first Latin American woman to be crowned as Miss Universe, and was crowned by Carol Morris of the United States.
USA - Miss USA 1957Leona Gage (MD), was announced as a semi-finalist, but she was ejected from the pageant the day before the final after it was discovered that she was married and the mother of two young children; therefore Miss Argentina, Mónica Lamas, who had placed 16th in the preliminary, took over the vacated spot and Gage was stripped off her title as Miss USA and was replaced by Charlotte Sheffield. However, Sheffield was not able to compete because the preliminary competition already took place with Gage competing in it, marking the first time that a Miss USA would not compete at Miss Universe. Sheffield would therefore compete at Miss World 1957 but was unplaced.
