This pairing of a black short sleeve shirt and a navy crew-neck t-shirt is great for off-duty days. If you wish to easily class up this ensemble with one single item, why not complement your outfit with a pair of black leather monks? This getup is our idea of perfection for baking hot summer afternoons. Ideal to show the world that even as a 20-year-old gentleman you're confident enough to hold your own in the outfit department.
