A navy double breasted blazer and a white v-neck t-shirt are the kind of a never-failing combination that you so terribly need when you have no time to dress up. A pair of white low top sneakers immediately ramps up the style factor of your outfit. This ensemble is also great if you're on a mission for summer wear to get through a tedious day. This combo is a shining example 40-something gentlemen can very well kill in the style department.
