>>10555416You have no idea what you're talking about. If you're wearing a waistcoat, you need to be wearing something dressy enough to match. Also, OP's shirt fits in a perfectly acceptable manner aside from his collar, but I know not if he has buttoned it...
Also, it's not a vest. It's a fucking waistcoat. A waistcoat. That is what it is called, and that is what it will be called from now on.
Also, OP needs to undo his bottom button. It is incorrect to do up the bottom button of a waistcoat.
As for the waistcoat itself, my own personal preference would be a plain grey fabric instead of that bastardised Prince of Wales pattern it seems to possess.
Now, to answer OP's question more directly: get rid of that particular waistcoat. Replace it with a waistcoat that exactly matches a pair of suit pants and a jacket, i.e. the third part of a three piece suit.
