Here are a few photos that might help you visualize how a Prince Charlie should fit. Basically the front is higher than with an Argyll jacket, having said that, as the traditional kilt is worn at the natural waist a higher front of the jacket is of little consequence.
This one was my first PC, as you will notice you can see a bit of my shirt front above the kilt, ideally you would not see this, however there is a learning curve and I was learning at the time, in fact this was a Christmas present from my family. I made the mistake of lending it out at it never returned.
