Gather top edge of skirt and pin to waistband right sides together. Sew.
Step 2: Making the bodice
For the top of the dress, choose a large or extra large shirt without a pocket. Cut the shirt across at the underarms, set aside the top of shirt to cut into squares later. Put the bottom of the shirt inside out on the dress form, or have a friend pin it around you. Pin the sides and darts. Unbutton and sew the front and back darts. Sew the side seams.
