Loving how this combo of a black waistcoat and blue jeans immediately makes any gent look sophisticated and sharp. Hesitant about how to finish off? Complement your outfit with a pair of white and navy leather high top sneakers to jazz things up. Undoubtedly, it's easier to work through a blazing hot hot weather day in a summery ensemble like this. Perfect if you're hunting for some seriously inspiring style for gentlemen in their forties.
