You can stay warm with a chunky sweater, thermal underwear, or extra layers. Complete the look with denim, leather, or bomber jacket. This would be a nice combo as an outfit for winter fashion for men. But make sure that you're under layers are visible to reflect the dressy vibe.

Another fuss-free winter style is donning grey, thick trousers with a white Oxford shirt, and casually throwing on a navy zip hoodie, all paired with white sneakers.

Opt for wool trousers in classic shades to keep warm while looking sharp. Accessorize with a leather belt and polished dress shoes. In colder climates, add a stylish topcoat or a well-insulated overcoat. Complete the ensemble with a scarf and leather gloves for a polished and warm winter business casual look.

Neutral tones such as oat and beige can help to bring a breath of fresh air to grey, navy, and black outfits, without having to wear bright colours. To add some interest, try experimenting with different textures such as a chunky knit or fine cord pants.
