You might be thinking of the painting Phryne Before the Areopagus. There’s a lot of variations on this painting. The general story is a man removes the clothing of a woman (usually being accused of sorcery/impiety) in front of a judge/jury in order to sway their opinion. Or to “prove” that her beauty was from God/gods and not something she bestowed upon herself with sorcery.
