A white and navy horizontal striped crew-neck t-shirt and navy chinos are a cool ensemble worth integrating into your off-duty rotation. Black and white canvas low top sneakers are a welcome complement to your outfit. As you can see here, this ensemble is a really good choice, especially for weird fall weather, when the mercury is dipping. Think you can't pull off modern off-duty dressing as you get into your 50s? This combo should prove you otherwise.
