The Waiting Adolphe William Bouguereau (1825-1905)

The picture has something of this: people, woman, portrait, girl, wear, beautiful, dress, veil, fashion, model, face, outdoors, brunette, style, nature, young.
Perhaps it’s a painting of a woman in a white dress with her hands on her chest, standing in front of a mountain landscape, with a pink sky in the background.
