A three-piece suit consists of a jacket, trousers and a waistcoat. It is a classic choice for weddings, celebrations and situations where you want a more polished impression. A waistcoat adds structure and keeps the outfit tidy even when the jacket is removed.

A waistcoat adds formality

For a groom or a formal guest, a waistcoat is an easy way to elevate a suit without making it too showy. Matching fabric creates a unified look, while a contrast waistcoat can add personality.

Fit is especially important in a waistcoat

A waistcoat should sit close to the body, but it should not pull at the buttons. The hem should cover the shirt waistband so the shirt does not show between trousers and waistcoat. A back adjuster helps fine-tune the fit.

When is a waistcoat not the best choice?

If the occasion is very relaxed or the temperature is high, a two-piece suit may be more comfortable. A waistcoat adds a layer, so fabric choice matters. A lighter wool or wool blend often works better than a very heavy fabric.

• Choose a waistcoat for weddings, formal events and representative dressing.
• Keep the waistcoat fitted, but not too tight.
• The bottom button is often left undone in the classic style.
• Consider temperature and choose fabric according to the purpose.
