Leaves are starting to fall and so is the mercury: autumn is well and truly upon us, whether we like it or not. So do your wardrobe a favour and fill it with a selection of versatile seasonal staples that will look great and keep you warm as the weather cools. From cosy cashmere knitwear to leather loafers, these are the non-negotiable men's clothes, shoes and accessories you should be stocking up on this autumn.

The jacket: Native North Utility Jacket

The utility overshirt is a year-round must-have, but this jacket really proves its worth in the autumn months as the ultimate layering piece. This workwear-style version from Danish label Native North is lightweight enough to wear over a sweater and under a thicker coat, with roomy pockets that you'll be thankful for when your fingers start to feel the chill.

The trousers: Uniforms for the Dedicated Corduroy Weave Volume Trousers

If you're looking for trousers that bridge the gap between smart and casual, you can't go wrong with cords. The rich, velvety texture of corduroy makes it an ideal fabric for transitioning into colder weather. Wear these black corduroy trousers from Uniforms for the Dedicated with just about anything — from a sweater and sneakers to smart loafers and an Oxford shirt.

The sweater: Artknit Studios Grey High-Neck Cashmere Knit

A high quality cashmere knit will transcend trends and stand the test of time, so invest wisely. This sweater from masters of knitwear Artknit Studios is ultra soft and supremely comfortable, making it a staple that you'll reach for time and again. We particularly love the elegant linear high neck, which offers a change from the classic roll neck.

The shoes: G.H. Bass & Co. Mid Brown Larson Pull Up Loafers

A pair of supple leather loafers in an autumn-appropriate shade of brown will be a timeless addition to any outfit, just as perfect for casual everyday wear as for more formal occasions. G.H. Bass & Co. are renowned as the original and best loafer makers, so do yourself a favour and nab a pair of the brand's iconic Easy Weejuns penny loafers.

The beanie: Escuyer Light Grey Ribbed Merino Beanie

A warm woollen beanie is a surefire solution to fighting the cold. This ribbed beanie from accessories experts Escuyer is made from 100% Italian merino wool, so it's guaranteed to do just the trick. Its durable construction means it'll see you through many autumns and winters.
