The conversation between human and AI assistant.
Why does Ahsoka wear suggestive clothing in Star Wars: The Clone Wars?
So, it was just for the sake of making her popular?
It is possible that the revealing elements of Ahsoka's costumes were intended to make her more visually appealing and help her become a more popular character. However, it is also possible that the production team felt that the designs were appropriate for her character and the situations in which she found herself throughout the series.
