A daytime business meeting
A navy jacket, a white or light blue shirt, navy or grey trousers and leather shoes. The socks are plain, in the colour of the trousers. With brown shoes, choose a brown belt and keep the socks navy or charcoal. The effect is calm but polished.
A formal dinner or evening event
A dark suit, a smart shirt, a tie and classic shoes. The socks should be predictable: plain, dark, without sheen or pattern. If the invitation calls for a dinner suit, in other words a black tie dress code, wear only fine, plain black socks long enough not to show your leg when you sit.
A wedding
A navy suit, a white shirt, black, brown or burgundy shoes and navy socks with a discreet texture or micro-pattern look elegant in photos and easy on the eye. Mind the length: on the dance floor your trousers move even more than at the table.
Smart casual
A jacket worn as a separate, trousers of a less formal kind and a shirt without a tie. Here socks can be a subtle accent: a texture or small pattern in the colours of the jacket and trousers. With beige or olive trousers, choose socks in a darker, calm tone that links the trouser colour to your shoes. With loafers, more of the sock shows than with lace-ups, so choose it with extra care. Dark brown leather penny loafers go well with a leather belt in the same shade of brown, finished with a textured silver buckle. You will find more outfits like these in our article on the smart casual dress code.
The rules for the two most common situations at a glance:
| Feature | Formal (business, ceremony) | Smart casual |
|---|
| Length | Mid-calf or over the calf, no leg showing when seated | Also long; with loafers more of the sock shows |
| Colour | Like the trousers or one shade darker, usually navy, charcoal or black | Still matched to the trousers, but warmer shades and mélanges are fine |
| Pattern | Ideally none, at most a very subtle micro-pattern | Small patterns and textures, as long as they do not dominate |
| Fabric and finish | Breathable, springy, matt or semi-matt | Breathable and comfortable, texture can be more visible |
