I have a green PC with matching 3 button vest. (see photo below) I would like to wear a 5 button vest with it some of the time. The company where I bought the PC does not have a 5 button vest in this color and I am hesitant to order one from some other place as I am sure it would not be the same shade of green.
Hence my question; can I wear a totally different color 5 button vest with this PC? If so, what colors would look best with it, black, navy blue or.....? I would normally be wearing my Stewart Hunting (ancient) kilt and not the Celtic Nations as in the pic below.
