Wear a dark green gilet with a white crew-neck t-shirt for a comfortable getup that's also pieced together nicely. Take an otherwise all-too-safe look in a more laid-back direction by slipping into dark brown leather sandals. There are a myriad of ways to look nice and survive the heatwave, and this here is one of them. Ideal if you're looking for some incredibly inspiring casual style for over-30 guys.
