A group of people is dancing in a public square

A group of people is dancing in a public square. They are dressed in folk costumes, with white shirts, dark vests, and patterned skirts or pants. Some wear head coverings, including scarves, hats, and elaborate headdresses. A few individuals wear large, shaggy costumes that obscure their faces. A Bulgarian flag is held aloft among the dancers. The square is paved with stone and is bordered by buildings. Other people, some wearing masks, are present in the background. The sky is overcast.
