For an off-duty outfit, reach for a white crew-neck t-shirt and a grey track suit — these pieces work nicely together. Now all you need is a pair of white athletic shoes to finish off your look. During the colder months, when practicality is crucial, it can be easy to surrender to a less-than-stylish getup in the name of practicality. However, this getup is a bright example that you can actually stay comfortable and remain stylish at the same time in the colder months.
