This pairing of a navy henley sweater and a charcoal crew-neck t-shirt is effortless, on-trend and extremely easy to copy. Rounding off with a pair of black leather work boots is an effective way to infuse a more relaxed finish into your look. Seeing as autumn is in the air, this ensemble is a wonderful pick for the transitional season. All in all, a perfect example of off-duty style for over-30 men.
