A young girl in a red dress (Girl with a letter) Konstantin Andreevich Somov (1869-1939)

The picture has something of this: people, wear, woman, costume, dress, portrait, dancer, girl, two, skirt, music, group, fall, princess, dancing, theater.
Perhaps it’s a painting of a woman in a red dress with a white ruffle around her neck and a crowd of people on the other side of her.
