Fold each short end over 1/2 inch. Fold the short end over another 1/2 inch. Press the folds in place. Sew all four hems in place.
Pin the panel into one side of the shirt through the sleeves with right sides together.
Sew both seams with a 3/8 inch seam allowance. Backstitch when you start and when you stop.
Pin and sew the other panel into the other side of the shirt. Finish the edges of the four seams with either a serger or a zigzag stitch.
Press the seam allowances towards the panel. Tack the seam allowance in place behind the hem.
