A large group of people, presumably high school students, are lying on the ground. Each pair consists of a male in a suit and a female in a dress. The girls wear an array of dresses in colors of black, white, blue, gold, and yellow with matching heels. They are positioned head-to-head and arm-to-arm. The image is taken from the side, revealing the whole group in a line. The backdrop is grass, with the sky blurred out.
