One standard pattern shape does not fit all figure shapes! Larger curvier buttocks need a curvier pattern angle in the back and flat buttocks need a flatter angle. The angle is as important as the width differences that are needed. This applies to the abdomen issues as well. Flat abdomens can have a flatter front but larger ones need a different shape to get the length and width needed. Learn a new and better way to alter for the abdomen. All legs are not the same either, full thighs, flat thighs, knock knees, bowed knees all have their own fitting needs as well.
