large group of teenagers in a gymnasium, dressed in what appears to be traditional or historical costumes. The boys are generally in dark uniforms with hats, while the girls are in long dresses of various colors, including red, green, and blue. They seem to be preparing for or in the midst of a dance, possibly a waltz or similar formal dance, moving in coordinated lines and groups. The gymnasium is well-lit with a wooden floor, basketball hoops on the walls, and large windows. There is a basketball near the ceiling of the gym. The camera angle is high, giving an overview of the entire scene.
