three piece suits

A sharper, more polished silhouette

Add a waistcoat and a suit transforms. The three-piece suit is the dressier, more deliberate cousin of the two-piece, and it has a way of making any man look like he means business. The matching waistcoat creates a clean, unbroken line from collar to trouser and keeps you looking sharp even when the jacket comes off. For weddings, formal events and anyone who wants to stand a cut above, the three-piece is the move.

What's included in a three-piece suit

A three-piece suit is made up of three matching pieces cut from the same fabric: a jacket, trousers and a waistcoat (also called a vest). The waistcoat is the defining feature, adding a layer of formality and a touch of old-school elegance. Because all three pieces match, the look is cohesive and considered, which is exactly why it reads as more formal than a two-piece.

When to wear a three-piece suit

Three-piece suits shine at occasions that call for a step up: weddings, black-tie-optional events, milestone celebrations and formal daytime ceremonies. They photograph exceptionally well, which makes them a favourite for grooms and groomsmen. The extra layer also makes them ideal for autumn and winter. In peak summer heat the waistcoat can feel warm, so many men simply remove the jacket and let the waistcoat carry the look.

The waistcoat: fit and buttoning

A waistcoat should fit snugly without pulling, long enough to cover the waistband so no shirt or belt peeks out beneath it. Follow the classic rule and leave the bottom button undone, a tradition that also gives you room to move. Worn with the jacket it looks formal and complete; worn without the jacket, sleeves rolled, it becomes a smart, relaxed look all of its own.

Colours, fabrics and styles

Choose deep, classic tones like navy, charcoal and black for formal events, or make an entrance in blue, maroon, green or a vintage pinstripe. Velvet three-pieces bring texture and richness to evening occasions, while pinstripe and check patterns nod to 1920s and Peaky Blinders style. Available in slim and classic fits, our three-piece suits are built to flatter and made to last.

Frequently asked questions

What is a three-piece suit?

A three-piece suit consists of three matching pieces made from the same fabric: a jacket, trousers and a waistcoat (vest). The added waistcoat makes it more formal and more layered than a standard two-piece suit.

When should you wear a three-piece suit?

Three-piece suits are ideal for formal and dressy occasions such as weddings, black-tie-optional events, formal daytime ceremonies and milestone celebrations. They are also well suited to autumn and winter thanks to the extra layer.

Is a three-piece suit good for a wedding?

Yes, three-piece suits are extremely popular for weddings. They look polished, photograph beautifully and help the groom and groomsmen stand out, while the waistcoat keeps the look sharp even when jackets come off during the reception.

Do you button the bottom button of the waistcoat?

No. Tradition and most modern styling leave the bottom button of the waistcoat undone. This looks correct and gives you more freedom to move and sit comfortably.

Can you wear a three-piece suit without the vest?

Yes. A three-piece can be worn as a standard two-piece simply by leaving the waistcoat off, which makes it a flexible, two-looks-in-one purchase. You can also wear the waistcoat and trousers without the jacket for a smart, relaxed look.

Is a two-piece or three-piece suit more formal?

A three-piece suit is more formal because the matching waistcoat adds an extra, dressier layer. A two-piece is more versatile and better for warm weather, while a three-piece is the stronger choice when you want maximum impact.
