At some point in his artistic career around the 1890s, James McNeill Whistler became obsessed with portraying the female form clad in diaphanous drapery. Inspired by Greek sculpture and Japanese prints, he developed this theme in all the media in which he worked, including transfer lithography, oil, pastel, and watercolor. The artist usually provided garments for his models, often classical gossamer gowns with high waists and crossed bodices paired with brightly colored kerchiefs. Most of all Whistler was looking for a perfect pose of his models; he sometimes asked them to dance about his studio until he caught the pose.
Hope you are having a dancing day! :)
