A grey blazer and a v-neck t-shirt are a nice ensemble worth integrating into your off-duty styling repertoire. For a modern on and off-duty mix, introduce a pair of white leather oxford shoes to your ensemble. During the winter months, when functionality is everything, it can be easy to surrender to a less-than-stylish look. This look, however, is a striking example that you can actually stay comfortable and remain stylish in the winter months. This getup looks great on middle-aged gentlemen.
