Costume designer for Final Fantasy X-2, Tsukamoto Tetsu states that the radical design changes for Yuna from Final Fantasy X to Final Fantasy X-2 reflect a huge cultural change. Because Yuna, Rikku, and Paine now lives in a more care-free world, the designers wanted them to be able to dress up. Scriptwriter Nojima Kazushige added that Yuna's new outfit was a "natural reaction to the heavy stuff she wore in FFX".
Beautiful cosplay! I love how the cosplayer looks as if she has a secret that she's not about to tell. Thanks again to Linda for her contributions!
