During the preliminary round of the evening gown competition, Quiambao slipped and fell on stage. As she walked, the heel of one of her shoes got caught in the trail of her evening gown and she slipped on the floor. Despite this incident she collected herself, regained composure, walked graciously, finished her walk, and drew applause from the audience. At the finals, Quiambao referred to the incident during an interview portion. She said "she felt she represented those women who have fallen both on and off the stage" and hopes to be "an example to the rest of the women in the world".
