Three Piece Suits

A 3-piece tailored suit is perfect for an occasion that calls for you to dress your absolute best. This suit style includes a jacket, waistcoat and trousers. Sometimes referred to as a men's full-piece suit, it’s typically worn for more formal occasions. So, if you're looking to buy your wedding suit or attend a wedding, a three-piece is a great choice. Coordinate and dress to impress by pairing it with a formal shirt, tie and shoes.

Styling a three-piece suit is all about letting the waistcoat take centre stage. Start with a crisp formal shirt – a cutaway or spread collar works particularly well. Your tie should be neatly knotted to sit flush against the shirt, with the tip tucked cleanly behind the waistcoat.

For your footwear, a smart pair of leather Oxford shoes or brogues is the perfect foundation. And the golden rule for the waistcoat? Always leave the bottom button undone. It's a time-honoured detail that ensures a comfortable fit and shows you know your tailoring.

A men's three-piece suit is your go-to for occasions that require you to look your absolute best. It's the definitive choice for a groom or groomsman, setting the wedding party apart with a unified, polished look.

Beyond weddings, a three-piece suit is perfect for other formal events like a day at the races, graduations, or formal award dinners. In a business context, it projects confidence and authority, making it ideal for that crucial presentation or high-stakes meeting where leaving a strong impression is essential.

Yes, and that's one of the best things about investing in a three-piece suit. It gives you true versatility and value.

• The Two-Piece: Wear the jacket and trousers together without the waistcoat for a classic business-ready look that's perfect for the office or less formal events.

• The Waistcoat: It's a powerful styling tool on its own. Layer your waistcoat over a shirt and pair it with chinosor different suit trousers for a sharp, smart-casual outfit.

When it comes to measuring your suit jacket, there are two things you need to keep in mind: chest size and sleeve size. Measuring the two correctly will help you find the perfect fit, whether you’re looking for a slim fit suit, tailored fit suit or regular fit suit. Head to our menswear size guide for UK/EU sizes available at Moss.

Depending on your build, the type of suit that suits your body and fits properly can vary. There are three main fits to help you find the best suit for you: slim fit, tailored fit and regular fit.

Slim-fit suits are tailored to fit closest to the body, right through to the seat and thigh. The fit is more modern, and tapered towards the ankle of the trouser. A slim-fit suit can give you a sharp and stylish look that’s still true to classic tailoring codes.

A tailored-fit suit is a well-balanced fit with a slightly tapered leg towards the ankle. Like a slim-fit suit, this fit is defined through the seat and thigh. A tailored-fit suit contours to the body for a flattering look.

A regular-fit suit is perfect if you’re looking for a nice balance between fit and comfort. The regular-fit suit includes straight leg trousers that hang smoothly over your shoes. It has a slightly fuller look compared to other suit styles right from the seat and thigh.

We recommend you buy your suit from a men's suit specialist with experts at the ready who can help you find exactly what you’re looking for based on your style, the occasion and your budget. Moss has those experts, and a variety of services so you can buy a men’s suit off the rack, get a custom-made suit, or even hire a suit.
