Choosing the Right Men's Suit for Work

The right work suit depends on your workplace dress code, how often you plan to wear it and the level of formality required.

If you need one office suit to cover several situations, choose a versatile colour and a clean, comfortable fit. You can dress it up with a tie and waistcoat for meetings or presentations, then wear it with an open-collar shirt on more relaxed office days.

Business Suits in Navy, Grey, Black and More

Colour can make a big difference to how often you can wear a business suit.

•   Navy suits are easy to combine with white, pale blue and patterned shirts, as well as black or brown shoes.
•   Charcoal and grey suits have a traditional business look that works particularly well for offices, interviews and client meetings.
•   Black suits have a more formal appearance and can also be worn for occasions outside work.
•   Blue suits offer an alternative to darker navy and can work well in offices with a less traditional dress code.
•   Checked and textured suits add more detail while keeping a tailored, professional look.

The collection also includes beige, brown, green and other colours for workplaces where there is more flexibility around business dress.

Work Suit Fits and Fabrics

A work suit needs to look smart while remaining comfortable during a full working day. Slim fits sit closer through the body and legs, tailored fits provide shape with a little more room, and regular or classic fits offer a less fitted cut.

The jacket should sit neatly across the shoulders without pulling when buttoned, and the trousers should fall cleanly without excessive gathering around the shoes.

Fabric is also worth considering if you wear a suit regularly. Lighter fabrics can be more comfortable during warmer weather, while heavier and more textured materials suit cooler months. Check the individual product page for fabric composition and care instructions.

How to Style a Suit for the Office

A white or pale blue shirt works with most business suits and gives you plenty of options for ties and accessories. Add a tie for formal meetings and client-facing days, or leave the collar open if the workplace dress code is more relaxed.

Black smart shoes pair particularly well with charcoal, grey and darker navy tailoring. Brown shoes work with navy, blue and many lighter grey suits. Changing your shirt, tie and shoes also makes it easier to create different work outfits using the same suit.

Men's Work Suit FAQs

What colour suit is best for work?

Navy, charcoal and grey are useful choices for regular business wear because they work with a wide range of shirts, ties and shoes. Black can suit more formal workplaces, while blue, brown, green and checked styles can work well where the dress code is less traditional.

Is a three-piece suit suitable for the office?

Yes. A three-piece suit can work particularly well for formal offices, meetings, presentations and client-facing roles. You can also wear the jacket and trousers without the waistcoat on less formal days, giving you more ways to use the same suit.

What fit should I choose for a work suit?

Choose a fit that looks neat but remains comfortable throughout the day. Slim fits sit closer to the body, tailored fits offer more room while keeping a shaped cut, and regular or classic fits provide a more relaxed fit.

Can you wear a checked or tweed suit to work?

Yes, if it suits your workplace dress code. Subtle checks and textured fabrics can work well in many offices. For more traditional corporate settings or formal interviews, a plain navy, charcoal or grey suit is usually the safer option.
