For me, the cream waistcoat adds very little that's good to this look. I'd also prefer darker shoes. Suit is really lovely though, and his shirt collar is too.
This guy looks terrible, even if he is wearing a 5K suit. A guy with his body and head shape should be wearing a skinnier suit with skinner lapels, period. And I don't give a shit what he thinks about it either, he looks ridiculous in this getup. The lapels on this thing are almost as wide as his entire face and the shoulders seem to be about seven times the width of his head.
