"Before the Mirror," Édouard Manet, 1876.
Y'all should know Manet by now, I won't bother going into his history.
Here we have a lady looking in a mirror; like some of Manet's other paintings, like "Olympia," it shows quite a bit of skin and may have hints of carnal activity. Unlike "Olympia" and other Manet paintings, this is done in a very broad, quick style.
Manet was often noted for the realism of his paintings, but here we have full-bore Impressionism. The dots of color in the background give a hint of floral wallpaper, and the whole scene is depicted in broad, quick strokes that nevertheless do a good job of telling us what we're seeing.
Manet loved to depict the modern world as well as intimate scenes, and this works well as both. Was it meant as erotica? Hard to say; some may have seen it that way in its time, but now it seems almost sweetly innocent.
