Портрет Екатерины II в дорожном костюме. 1787 Mikhail Shibanov (1700s)

The picture has something of this: people, portrait, wear, leader, royalty, necklace, man, woman, dress, veil, jewelry, lid.
Perhaps it’s a close up of a painting of a person wearing a red coat and a black hat with a gold chain around his neck.
