Angelic Pretty Dreamy Horoscope JSK?

Hi everyone, I was looking at Angelic Pretty and the Dreamy Horoscope (white) looks nice, and I'm thinking about saving up for one. One problem that's making me hesitant is that on the display it looks a bit funny. Did anyone purchase this in a jumperskirt and have it either look good or bad on them? Did you need to bring in the waist or anything?
Thanks! <3
