Ophelia John William Waterhouse (1849-1917)

The picture has something of this: dress, woman, beautiful, girl, princess, people, fashion, nature, nymph, fairy, model, tree, portrait, outdoors, person, traditional, fantasy, fairytale.
Perhaps it’s a painting of a woman in a blue dress with flowers in her hair standing in a wooded area next to a tree with a bridge in the background.
