Hello ladies once again! For the front placket the finishing is very simple as it is a simple front; the raw edge on the inside of the facing can be either serged or folded under like a rolled edge, once that is done finish the hemline with a rolled edge. You can start right from the outermost edge with the facing open and fold it over and stitch in place over the stitching line or fold the facing first and then do the rolled edge at the hemline, either way is acceptable.
I will try and take some pics of what I am trying to explain in the meantime take a look at ready made shirt and see how the front is finished just to get an idea.
