I agree... in X-2, Yuna mentions that Spira's people are more upbeat, that they're taking the time to enjoy themselves now that Sin's ever-present menace is gone. Rikku could be seen as an 'embodiment' of that change.

maybe she's just more slutty is all. her clothes say so.
I'm not so sure. She's wearing less, certainly, but very little she ever says or does suggests any kind of promiscuous tendencies.
