Сountess R. Zubova Zinaida Serebryakova (1884-1967)

The picture has something of this: portrait, people, veil, wear, lid, woman, vintage, retro, fashion, necklace, jewelry, crown, royalty, dress.
Perhaps it’s a drawing of a woman wearing a hat with flowers on the top of her head and a necklace with pearls on the bottom of.
