Business casual is the default in many UK offices, and for work events outside the boardroom. You're showing you're at work, without the formality of a suit and tie.
What to wear, piece by piece
- Jacket
- A blazer is optional but useful for meetings. Navy, grey or a subtle check.
- Top
- A shirt or smart polo, no tie needed. A fine knit over a shirt works in colder months.
- Trousers
- Chinos or wool trousers in grey, navy, stone or olive.
- Shoes
- Leather shoes, loafers or suede boots.
- Extras
- A belt that matches your shoes, a tidy bag, and a jacket on the back of your chair for unexpected meetings.
What to avoid
- Jeans and trainers, unless the office is clearly relaxed.
- T-shirts with logos or slogans.
- Shorts and sandals, even in summer.
Two ways to wear it
Keep it classic
Navy blazer, white Oxford shirt, grey wool trousers and brown leather Derbies.
Push it a little
Grey merino crew neck over a light blue shirt, olive chinos and brown suede Chelsea boots.
Quick questions
Is a polo shirt okay?
A smart knitted or piqué polo in a plain colour is fine. Tuck it in if you're wearing a jacket.
What about Fridays?
Most offices relax further. Dark jeans with a shirt and blazer are usually safe.
Do I need a blazer every day?
No. Keep one at work for meetings and presentations, and wear a shirt or knit the rest of the time.
