Portrait of Ekaterina Nikolaevna Davydova (1750–1825) Vladimir Borovikovsky (1757-1825)

The picture has something of this: portrait, people, wear, woman, outerwear, retro, writer, jewelry, facial expression, music, actress, necklace, musician, turtleneck, knitwear.
Perhaps it’s a close up of a painting of a woman wearing a blue dress with a white scarf around her neck and a necklace hanging from her neckline.
