For work, pair a long tailored coat with sharp trousers, a fine-gauge knit or shirt, and structured footwear to keep the vertical line clean. Off-duty, the same coat can sit over denim, wide-leg pants or a hoodie for a more relaxed contrast. Neutral colours make it easy to rotate between occasions, while bold shoulders or pattern can become the statement over simpler bases. Adjust the silhouette with belts or open-front styling depending on how directional you want the look to feel.
