The Great British winter seemingly does two things to mankind: first, it takes its weather patterns with an enormous pinch of unpredictability, and then it allows them to assume that style rules no longer apply.

Let us start by telling you that style rules always apply, come rain or shine. If anything, winter is more important. Once you’ve got to grips with the basic dos and don’ts, the art of layering the suit is simple, and will make any adventure into the great outdoors a much more stylish one.

Keep up with the world’s best-dressed men by swapping your shirt for a rollneck. Not only will this keep your core temperature at a comfortable level, but in darker colours it’s a great way to flatter your body shape. Can’t see yourself rocking this look? Then go for a crew or V neck, but always with a shirt. Worn alone, they will automatically deconstruct your suit, making it immediately more casual. The final word? Keep all knitwear slim fit, neutral in colour and pattern and never let it outshine your suit.

Down jackets have fast become one of winter’s most popular pieces, and for good reason. This year, take the trend one step further by layering a down gilet underneath your suit: something you’ll see street style stars all over the world wearing when the temperature drops. Unify colours by choosing two similar shades: contrasting tones in this situation are going to do you no favours. Remember, you’re not trying to replicate the three-piece, instead you’re creating a bold, unstructured look that’s guaranteed to elevate your style game.

The overcoat: it’s not rocket science, but it works. Layering a tailored cover-up with your everyday suit will raise the bar in more ways than one. By introducing an extra collar, opposing hemlines, plus different colours and textures to your suit, you’ll instantly upgrade your sartorial status from ‘man in suit’ to ‘impeccably-dressed man in suit’. Any variation on this type of outerwear works, whether you choose a mac, a thick and textured longer overcoat or a thin, tailored one – avoid shorter jackets though, as they don’t tend to have the same effect. Finally, and most importantly, make sure it fits you properly, and then you’re all set for your best winter look yet.
