formal evening dress: vest or no?

[CMcG]

OK, thanks to this thread I decided that having a 3 button vest to go with my Spencer jacket would be a good option. I found one on sale and it should be here fairly soon.

The vest I purchased has satin lapels on it and, from photos I've seen, that seems fairly common. Is that standard on most 3 button vests intended for PC type jackets?

Generally the lapels on the waistcoat are of the same fabric as the body of the PC. That said, there is no reason whatsoever that satin lapels on the waistcoat would be regarded as inappropriate. This is truly a case of personal style, nothing more. Nothing less.
