You do not need a waistcoat with a suit, but it adds formality and polish. Wear one for weddings, dinners and formal events; skip it when it is hot or the occasion is casual. A 3-piece suit gives you both options. At Suit Archive, the waistcoat is included in the $178 suit.

What a Waistcoat Does
A waistcoat covers the shirt and tie, creates a clean vertical line and adds a layer of formality. It also hides the shirt waistband, so the whole outfit looks more streamlined.
