Evening waistcoat vs suit waistcoat

An evening waistcoat is cut low in a U or V shape, short and with few buttons, so it shows the front of the dress shirt. A suit waistcoat is high-necked and longer, usually with five or six buttons, and covers most of the shirt front. Because the cut differs from the start, a suit waistcoat cannot stand in for an evening waistcoat under a tuxedo.

The evening waistcoat: low cut, shirt front on show

An evening waistcoat has a low neckline, U or V shaped, deep enough to show the dress shirt front, the bow tie, the studs and the wing collar. It is short, just covering the trouser waistband. It has few buttons, usually three to four, and many designs are backless, held by an adjustable strap behind.

The purpose of this cut is to hide the join between shirt and trousers, keeping the line from chest to waist unbroken while still letting a pleated or piqué shirt front show. TUX-093 has a U-neck double-breasted waistcoat with satin-faced buttons, a white bow tie and a lily pin, an example of classic gala style.

The suit waistcoat: high neck, many buttons

The suit waistcoat is the waistcoat of the business three-piece. The neckline sits high, close to the tie knot; it is longer; and it has five or six buttons from neck to point. The back is lined and adjustable. It is designed to cover the shirt front and sit neatly beneath a necktie.

With a bow tie, a high-cut waistcoat peeks out right beside the bow and hides the dress shirt, making the whole look closer to a work outfit than evening dress.

Lapels, buttons and cloth

Detail	Evening waistcoat	Suit waistcoat
Neckline	Deep U or V	High, covering the chest
Length	Short, just covering the waistband	Longer, falling past the waistband
Buttons	About three to four	About five to six
Edging	May be edged or faced in satin at neck and buttons	Usually the same cloth as the jacket
Button type	Satin-covered or small flat metal	Same material as the jacket buttons
Cloth	Tuxedo wool, or satin, silk, velvet	Same cloth as the suit
Back	May be open with a strap only	Closed lining

On a double-breasted evening waistcoat like TUX-093, the buttons are covered in the same satin as the lapels, creating a second layer consistent with the jacket.

Why a suit waistcoat does not belong with a tuxedo

There are three main reasons:

1. The high neckline hides the shirt: a tuxedo is meant to show the dress shirt front, and a high waistcoat covers it.
2. The buttons and cloth are wrong: a suit waistcoat is usually in matte suiting wool, with no satin or covered buttons, which clashes with satin lapels and braided trousers.
3. The spirit is wrong: a suit waistcoat suggests the office, and paired with a bow tie it no longer reads as correct black tie.

If you are having a three-piece tuxedo made, tell your tailor you want an "evening waistcoat", not a "suit waistcoat". The styles available are laid out in styles of waistcoat for the three-piece tuxedo, and the choice between waistcoat and cummerbund is covered in three-piece tuxedo: waistcoat or cummerbund.

When a suit waistcoat is right

A suit waistcoat is entirely appropriate in a three-piece suit with a necktie, whether at work or at a lounge suit event. It is also a way to add a warm layer to an ordinary suit in cold weather. Only when you switch to a tuxedo and bow tie do you need to change to an evening waistcoat.
