Group Portrait of Mary, Charlotte, Caroline and Eliza, daughters of Christopher and Anne Gullett John Opie (1761-1807)

The picture has something of this: woman, people, two, portrait, veil, dress, wear, lid, group, three, fashion, model, theater, costume, child, girl, queen, four.
Perhaps it’s a painting of three women sitting on a bed with one of them holding a young girl’s hand and the other.
