Nude tanned torso Félix Édouard Vallotton (1865-1925)

The picture has something of this: people, nude, portrait, woman, man, artistic, shirtless, son, wear, fashion, Renaissance, model, jewelry, veil, girl.
Perhaps it’s a painting of a naked woman standing in front of a mirror with her hands on her hips and a towel hanging from the side of her body.
