I’m sure this has been asked before but I can’t find the answer- sorry!

So, is there any serious reason that 5 button waistcoats shouldn’t be worn with PC jackets? Asides from tradition.
It does seem to be something the hire places will do much more nowadays, and I personally much prefer it to 3-button waistcoats. Opens up the arena to Cravats and regular ties, asides from just bows.

Anyone have any thoughts? Much appreciated!
