If there's one thing we're sure about, it's that 'sweater weather' has officially arrived. Looking for a timeless take on it that you can rely on year after year? A trusty roll neck - as proven by both the Princess of Wales and Sophie, Duchess of Edinburgh on multiple occasions - is the answer. While Kate tends to favour dark or earthy colours when it comes to her turtle neck knits, Sophie often turns to neutrals, going for cream, white and camel tones.

Looking to level up your own layering this autumn and winter? There are a whole range of roll necks to choose from; from chunky jumpers and cashmere knits to slinky under-layers, depending on the occasion. Sophie, Duchess of Edinburgh has worn stylish roll neck jumpers to a wide range of events, including military cups and Christmas celebrations.
