Portrait of Catherine II Fyodor Rokotov (1735-1808)

The picture has something of this: people, necklace, portrait, jewelry, dress, woman, fashion, queen, wear, choker, model, girl, princess, veil, brunette, bracelet, gold, crown, vintage.
Perhaps it’s a close up of a painting of a woman with long hair wearing a blue dress and a tiara with a bird on it’s head.
