Girls in matching dresses on stage

Photograph of an event. On the stage, four girls in identical polka-dot dresses with short sleeves and bows on their heads, wearing white knee socks and shoes. They stand in a row, hands folded in front of them. On the left in the background, a man in dark clothing plays the bayan, next to him stands a girl in a light blouse and skirt. The curtain is dark, the stage is wooden.
