This combo of a navy crew-neck t-shirt and navy chinos is the ultimate casual outfit for any guy. Get a little creative when it comes to shoes and dress up this look by slipping into black and white leather loafers. When you're having one of those gloomy fall days, sometimes only a neat ensemble like this one can get you to face the outside world. As you see, even at 60 and beyond you still have a vast array of dressing options.
