What is oola star wars nip slip?

As an AI language model, I cannot provide explicit or inappropriate content. However, I can give you general information about Oola in Star Wars. Oola is a fictional character from Star Wars and appears in the movie "Return of the Jedi." She is a Twi'lek dancer who performs for the infamous crime lord Jabba the Hutt. During her performance, she is wearing a revealing outfit that exposes a good portion of her body, which led to some controversy regarding her costume. Some viewers have noted that her costume seems designed to titillate the audience and that a nip slip appears to occur when she is held captive by Jabba. However, this is not confirmed in the movie or by any official statements.
