Hello, I am working on a costume from Fate Grand Order, Mysterious Heroine X Alter. I am working on her third ascension and I have most pieces figured out except for the jacket. It looks like it is in long stripes with seams going long ways down the jackets, but there is no seam at the waist. I'm not sure how to make this and have all the stripes lined up when the jacket is so much bigger and wider at the bottom that it is at the waist/shoulders? Any ideas/recommendations?
