I will now list my favorite Rikku Dressphere looks.
Note: All of these look a billion times sexier in game.

Lady Luck


If I remember right she has a special move where she blows a kiss... I need to replay X-2.

Samurai


Is there anything more adorable than watching her "oomph" that ridiculously huge katana up when attacking?

Berserker


Watching her breakdance the enemy to death is pretty hot.
