Smart casual turns up on invites for everything from team lunches to fortieth birthdays, and it trips people up because it's so broad. Think of it like this: no suit and tie, but nothing you'd wear to the gym. One smart piece and one relaxed piece usually gets it right.
What to wear, piece by piece
- Jacket
- A blazer, overshirt or good knit as your top layer. An unstructured blazer in navy, grey or brown is the most useful thing you can own.
- Top
- A casual shirt, a knitted polo, a fine knit, or a plain T-shirt under a blazer.
- Trousers
- Chinos or wool trousers; dark, unfaded jeans at the relaxed end.
- Shoes
- Loafers, Chelsea boots or Derbies; clean minimal leather trainers only when the setting is clearly relaxed.
- Extras
- A belt that matches your shoes. No tie needed.
What to avoid
- Gym trainers, hoodies and sports tops.
- A full suit and tie, which is too formal.
- Shorts, unless it's a summer daytime event and you know the crowd.
Two ways to wear it
Navy blazer, light blue Oxford shirt, stone chinos and brown suede loafers.
Brown checked overshirt worn open over a cream roll neck, charcoal trousers and white leather trainers.
Quick questions
Are jeans smart casual?
Yes, if they're dark, well-fitting and unfaded. Pair them with a smarter top layer such as a blazer or overshirt.
Can I wear a suit?
A suit with a knit or open shirt can work, but it can look overdressed. A blazer with contrasting trousers sits better.
What's the easiest smart casual formula?
A navy blazer, a plain shirt or knit, dark trousers or jeans, and clean leather shoes. Then change one piece at a time to suit the event.
