A black crew-neck t-shirt and black jeans are the kind of a never-failing off-duty ensemble that you so desperately need when you have no extra time. Introduce pink low top sneakers to the equation and you're all set looking boss. Keep this look in mind when warmer days are here, and rest assured, you'll save time brainstorming for what to wear on more than one morning. Overall, a great example of casual style for 40-year-old gentlemen.
