The days of ‘suit, shirt, tie’ business wear simplicity have passed and business casual is on the rise. This might sound confusing – the name itself is something of a contradiction – but trust us, it’s worth persevering.

At its most basic, business casual means pairing smart and casual pieces. You’ll also find it helps to think of this as a spectrum: some looks are smarter, others more relaxed. Here we share the wisdom of Jermyn Street and seven sharp looks to help you master the new office style.

Business casual is your licence to experiment, and that can mean playing up the formality as well as dialling it down. This look features a waistcoat and tie – two classically formal pieces – but their knitted construction recasts them with a new casual effect. A patterned pocket square completes the playful impression.

Knitted layers

Wearing knitwear, such as this soft knitted waistcoat, beneath a blazer is a great way to work in a laidback layer.

Add punch with pattern

Lighten more formal looks with contrasting patterned accessories, such as this pure silk pocket square.

The perfect look for the man who is just dipping his toe in the waters of business casual. The classic neutral navy colour scheme makes this a natural fit for the office, while the check shirt lightens the ensemble and the chinos offer an easygoing alternative to the formal trouser.
