A little girl and a young woman, probably her older sister judging by the red hair, wait by an iron fence in Édouard Manet’s 1872-73 paintingThe Railway.
Little girl’s clothing in the early 1870s was often sleeveless and usually had very low cut necklines, sometimes even off the shoulder completely.
Look at the rendering of that dress and the brilliant use of neutrals in the background, or the puffiness of that smoke!...
