I personally think that the decline of the vest was a result of war-rationing, and improved heating.
For most of history, if it was cold outside, it was also cold inside. Buildings had little insulation or heating (unless you count fireplaces). And often, it was colder inside than it was outside. So wearing a three-piece suit, or a vested two-piecer, was essential to keeping warm.
As things like central heating improved, waistcoats became less and less common as they provided an extra layer of warmth which wasn't, strictly speaking, required anymore.
