Sofia Charlotta (1744-1818), Princess of Mecklenburg-Strelitz, Queen of England Georg David Matthieu (1737-1778)

The picture has something of this: people, woman, portrait, dress, wear, girl, veil, fashion, retro, bed, vintage, reclining, model, princess, gown, necklace.
Perhaps it’s a painting of a woman in a white dress sitting on a blue chair with a fur stole around her neck and a book in her left hand.
