With the ever-increasing relaxing of dress codes (read: a newfound collective obsession with loungewear) it's never been more important to master smart casual style. Calling for comfort and elegance in equal measure, it's notoriously tricky to pull off and all-too-easy to get wrong, but get the balance right and you're golden. Not quite sure where to start? Cut through the confusion with our straightforward guide to mastering the smart casual dress code...

What is the smart casual dress code?

Quite literally a combination of two opposing dress codes, smart casual is a rather elusive concept that's open to myriad interpretations. It differs slightly from the business casual dress code in that it's slightly less formal and not strictly limited to an office setting. Rather, this is a dress code that's ideal for a nice dinner, elegant drinks event or even a wedding (when the invitation specifies it).

The key to mastering smart casual style is to give weight to both sides, ensuring your outfit is neat and sophisticated but not stuffy. If in doubt, it's always safest to lean more towards the 'smart' end of the spectrum, opting for classic silhouettes, tailored cuts and tasteful neutral hues.

What counts as smart casual?

Technically, almost any item of clothing — except for sweatpants — could qualify as smart casual. The context of the rest of your outfit is crucial. For example, a crisp and clean white T-shirt is an effortless smart casual fail-safe if teamed with tailored trousers and a suit jacket. Dark blue or black denim jeans (as long as they're not ripped, bleached or too tight) can be smart casual when worn with loafers and an Oxford shirt. Other smart casual staples include ever-versatile chore jackets, chinos, which are less formal than suit trousers but smarter than jeans, knitted polo shirts, grandad collar shirts, roll neck knits and the true hero of any smart casual wardrobe — a deconstructed navy blazer. Opt for well-cut pieces in high quality materials to avoid a scruffy look.

When it comes to footwear, elegant leather trainers in a single classic hue are totally appropriate and will lend a casual edge to more dressy attire. Loafers, derbies and brogues are also reliable options. Keep accessories timeless: a well-made leather belt, dress watch and simple cord bracelet will complement rather than take away from the rest of your outfit.

What not to wear when the dress code is smart casual

If it's something you tend to wear around the house — old jeans, threadbare tees and the like — save it for hangover days in front of the TV. Sportswear should also be avoided for the most part, unless it's a particularly sleek pair of sneakers or tailored technical jacket (grey marl is a no-go). Bold colours, garish prints and loud patterns should feature sparingly, if at all. Unless you're 100% confident in your statement-making garb, keeping things classic is always the best bet.
