The polo shirt solved a problem that neither the T-shirt nor the casual shirt quite manages: how to be simultaneously relaxed and put-together without appearing to have tried. The collar does the work. In the right weight of piqué or jersey, in a colour that works with the trousers you already own, a well-made polo shirt is among the most efficient pieces of dressing available. These are polo shirts from makers who understand the garment: Gran Sasso, Fedeli, Eton, Canali, and others who produce them in fine cotton, silk-cotton, and merino with the same attention to fabric and fit that they bring to everything else.
