In Trouble

So, I want to make this dress. I have the pattern cut, the fabric cut, and even the pleats made. However, I cannot figure out how to attach the bib-type insert on the front of the dress. The instructions on the pattern say to put right sides together and sew. If I do that, the edges don't line up. I can't figure it out and so I'm calling on all my sewing/design friends to help give me a clue. Am I supposed to match up the shoulders or line up the raw edges or what? It isn't very clear and I can only sew once (it's a brocade), so I can't mess up and do a redo. It'll ruin the fabric. Suggestions? Help!!
