Tux with tails to Prince Charlie conversion

[Panache]

Taking a cue from Prester John's wife I am looking to convert my old tuxedo jacket* with tails (being it is of good quality and condition) into a Prince Charlie. I am thinking of using the diamond shaped thistle buttons from Three Feathers Pewter

My friend Gryphonaire is going to loan me his PC to take with me to the Tailor's shop so we have a model to go by.

I had a few questions.

I was wondering about the vest for a Prince Charlie. Most of the pictures I have found of PC jackets show them worn with a very low vest with a mere three buttons. Can a taller vest with more buttons be worn or is that not true to the PC look?

Are all the buttons on a PC jacket the same size? Or are the cuff and epaulette buttons smaller like the vest buttons?

Is the PC always to be worn with a vest (I've seen a few pictures showing it worn with a belt and no vest)?

Lastly if any one has pictures of themselves in a PC (preferably both front and back) I'd love to see them.

Anyone who has done this/ had it done I'd love any tips.

Cheers


* The pants that I have to go with it are obviously of inferior quality, having shrunk to unreasonable size whilst sitting in my closet for the last decade. That is my tale and I am holding fast to it.
