Size-mismatched PC and vest—what to do?

[OC Richard]

I've worn my Prince Charlie with waistcoat and without, both looks are fine.

As was suggested above I did wear a bow tie with either look, and when not wearing a waistcoat I wore a belt.

I wouldn't worry too much about matching fabrics- in my experience proper UK Barathea generally matches well enough.

I will note that the black "Barathea" waistcoats that our band members purchased from J Higgins weren't a true black and didn't match in well with our UK-made jackets.

I did have to alter a Prince Charlie style waistcoat I bought ex-hire on Ebay; though not listed as "long" it was.

Happily the arm-holes were long ovals so all the tailor needed to do was to take in the shoulder seams a couple inches.
