That's not at all slutty nor quite like the outfit of a Geisha. I've seen much worse and sleazier outfits.

Anyways ...

Unlike a lot of other characters - female especially - she grows up and develops. In FFX, we see the kind, self-sacrificing, and devoted sides of her. She keeps all of those in X-2 but actually better stands up for herself, becomes more independent with herself and abilities.

This isn't as common of a feature, sad to say, as it should be in many games - regardless of genre. Or fandoms at that matter, really .. any type of source for entertainment I suppose is the better wording.
