So as you can see, looking casually sleek doesn't require that much effort. Team a grey blazer with white chinos and you'll look amazing. A trendy pair of black suede tassel loafers is an easy way to add a little kick to the ensemble. As you can see here, this combo is a really smart choice, especially for in-between weather, when the mercury is dropping. Overall, a perfect example of smart casual style for middle-aged gents.
