In order to tweak the fit, I slipped the skirt on inside out. I decided not to do a center back seam alteration. Instead, I will use elastic between the skirt and the facing. I have some elastic that I purchased from Emma Seabrook at the Sewing Expo. I bought an entire roll. This stuff is not like the rubbery elastic at JoAnns. It is 3 inches wide and it is soft and has good recovery. This will keep the waist from stretching too much.
