This combination of a grey overcoat and a white crew-neck t-shirt is a foolproof option when you need to look dapper in a flash. A pair of white and black canvas low top sneakers adds a new depth to this ensemble. When it's one of those dreary fall days, sometimes only a killer getup like this one can get you to face the outside world. Those who wonder how to sport cool off-duty dressing as you move through your adolescence, this getup should answer your question.
