Portrait of Lewis Bagot, Bishop of Bristol (1740-1802) Thomas Gainsborough (1727-1788)

The picture has something of this: people, portrait, man, wear, music, facial expression, outerwear, jacket, lid, menswear, elderly, wig, woman, leader, necklace, vest.
Perhaps it’s a close up of a painting of a man in a black coat and white shirt with a white shirt on and a black blazer.
