Excess in the bottom bit I'm guessing? Did you take any length out at any stage, cos it has a knock on effect?
Anyway, easy fix. Line up the centres of the bottom rectangles, withe the centres of each section of the top bit, ie CF, CB, and side seams. Work from the middle to corners, and where there is excess, take it out of the bottom along the seam line. It will all balance. Remember the odd tuck gather or pleat won't show when you're wearing it as it's very forgiving
