John Singer Sargent was a perceptive observer of people. His paintings suggest the character of the subject through posture, subtle hand gestures, and masterful depictions of expressions.
For example, the folds and curves of the dresses of his society women are a waterfall of loose colorful brushwork that combines to suggest a rich fabric captured in motion. And the faces are solid and sure, but at the same time soft, depicting small nuances of expression.
