For an outfit that's very simple but can be modified in many different ways, dress in a shirt jacket and a navy and white crew-neck t-shirt. For something more on the casual and cool end to finish this outfit, go for multi colored athletic shoes. This ensemble is a practical illustration older gentlemen can still very well kill in the style department.
Choose a shirt jacket and a navy and white crew-neck t-shirt for comfort dressing with a fashionable spin. Complement your outfit with a pair of mustard canvas low top sneakers to make a classic ensemble feel suddenly fresh. Think you can't pull off edgy casual dressing as you slip into your 60s? This combination should prove you otherwise.
