Styling a luxury overshirt involves balancing elegance with casual sophistication. Opt for high-quality fabrics like silk, cashmere, or fine wool. Pair it with tailored trousers or dark denim for a sleek look. For a refined touch, add a statement belt and polished loafers or dress shoes. Accessorize with minimalist jewelry and a classic timepiece. Layering is key: wear it over a fitted turtleneck or a crisp white shirt. Finish with a tailored coat or a structured blazer for a polished ensemble.
