Rikku's outfit changed from a casual outfit to a skimpier outfit from "Final Fantasy X" to "X-2". Tetsu Tsukamoto, the alternate costume designer, explains that the change could come from the changes in Spira from the two titles from a "darker, religious feel". The decision to pick Rikku as one of the three female leads came early on in the design process of "X-2", due to the developers challenging themselves to create an all-female character party. Yuna and Rikku were the original choices.
