Measure the length of the zip and sew the placket pieces together to be the correct length to fit your zip, just like a regular zip placket. The difference is shaping the placket with the "nose". The point of the nose has to be at the same level to where the zip pull sits when it is closed. Turn out the placket, finish the long raw edges together, and put in a buttonhole of a size to suit your chosen button.
