One of the best ways for a man to style out a white crew-neck t-shirt is to marry it with grey chinos for a casual look. You can get a little creative when it comes to footwear and tone down this getup by rounding off with a pair of black and white athletic shoes. So if it's a roasting hot warm weather afternoon and you want to look on-trend without exerting much effort, this look will do the job in no time. Those wondering how to pull off cool casual looks as you work your way through your teens, you have your answer.
