A vest should be worn with the Prince Charlie.

Very nicely explained, Alaskan.

Actually, I believe the Argyll in anything other than tweed to be a fairly modern and recent innovation. Not so many years ago, one could find Argylls only in Lovat Green or Lovat Blue - unless the purchaser went 'bespoke'!

My black "Argyll" is actually called a Crail Jacket!

Also, I would not swear to it, but I do not think one can buy a Prince Charlie without the vest/waistcoat. Mine certainly came with one.
