If you like a more laid-back approach to dressing up, why not wear a white and navy print crew-neck t-shirt and olive chinos? White leather low top sneakers tie the outfit together. So if it's a hot summertime day and you want to look dapper without putting too much effort, this look will do the job in no time flat. Those who wonder whether you can still pull off modern casual style as you move into your 50s, you have your answer.
