Helene de Rua, Princess Jean de Merode Zinaida Serebryakova (1884-1967)

The picture has something of this: people, portrait, woman, wear, dress, model, jewelry, lace, necklace, fashion, tattoo, nude, retro, veil, gown, swerve.
Perhaps it’s a painting of a woman in a blue dress with a pearl necklace on her neck and her hand resting on the arm of another woman’s arm.
