First thing you want to do, after ironing all your yoke pieces, is match the shoulders right sides together and pin the front pieces to the back. Sew along the shoulder seams with a 1/4 inch seam allowance. Repeat for the yoke lining. You should now have what is pictured above.
Now press your shoulders seams open, then fold and press the bottom of each yoke 1/4 inch to the wrong side.
Put the wrong sides together then baste the yoke and lining together around the neckline. Pin and baste your length of broderie anglaise trim along the bottom edges of the front yoke pieces (this is optional. In my first dress I used ric-rak instead). The right side of the top edge of the trim should be facing the wrong side of the bottom edge of the outer front yoke.
