At GH, we’re all about the wardrobe staples that stand the test of time, and if there’s one piece that never goes out of style, it’s a trusty Fair Isle knit. Once the signature of Scottish fishermen, it has since become a sartorial favourite among well-dressed women, making a comeback year after year when the weather gets chilly.

It comes as no surprise, then, that now we’re firmly in autumn, the high street is brimming with Fair Isle knits. But if we had to pick just one, our vote goes to a particularly chic M&S version, which combines the classic geometric pattern with two of this season’s key colours: bitter chocolate and ecru.

Its rich bitter chocolate base will lend itself seamlessly to any autumn wardrobe, pairing effortlessly with everything from dark denim to trousers in deep burgundy and khaki. Meanwhile, the soft ecru pattern adds an airy contrast.

Then there’s the texture. This season is all about tactile finishes, from ultra-fluffy cardigans to chunky cable knits. M&S’s Fair Isle has been given the same treatment, with a softly brushed finish, giving the heritage pattern a fuzzy upgrade.

Now, I’ll confess, over the past few years, I’ve found myself gravitating almost exclusively towards boxy, oversized knits. But this jumper has reminded me just how brilliant a slim fit can be. Cut to softly skim the silhouette, it creates a clean, tailored look that looks effortlessly polished from the moment you pull it on.

It’s this fit that makes it an easy win for office dressing. For day-to-day wear, simply pair it with your favourite pair of jeans, or smart pleated trousers and ballet pumps. Or, for full heritage chic, take a cue from Claudia Winkleman’s Traitors wardrobe and try pairing it with a kilt (in plaid for contrast) and a great pair of boots.
