And with it comes a whole new aesthetic for men's fashion. Comfort and warmth are prioritised over fashion, and darker, richer colours replace the light pastels of the summer.

Luckily, your favourite designers have nailed men's knitwear this year, with a selection of stylish knits that are incredibly wearable.
