This combo of a black print crew-neck t-shirt and blue jeans is definitive proof that a safe casual outfit doesn't have to be boring. To give your overall look a more polished touch, why not opt for a pair of black leather oxford shoes? This getup is a viable option when it comes to a knockout ensemble that transitions easily into fall. Those who are dubious whether you can still sport cool off-duty style as you go into your 40s, this combination should answer your question.
