Things You'll Need
Instructions
Turn the shirt inside out and try it on. Pin along side seams where you want the side seam lines to be so the shirt fits more tightly.
Cut a slit down the top of the sleeve under the shoulder seam. Pin the shoulder seams up to tighten the sleeves.
Open the shoulder seams with the seam ripper and take in the fabric as desired; pin it in place.
Measure how far you want to take up the hemline around the bottom of the shirt.
Divide the length measurement in half and fold the fabric over according to the quotient. Fold the fabric over the same length again and iron the fold line. Sew the hemline in place.
Sew the new side seams and shoulder seams. Stitch down the sleeves where you have placed pins and trim off any excess fabric.
