A white turtleneck and charcoal jeans are the kind of a no-brainer casual ensemble that you need when you have no extra time. Go off the beaten path and spice up your ensemble by slipping into a pair of black athletic shoes. On not so cold afternoons, you can rock a version of this summer-to-autumn getup and look absolutely awesome. Just because you're in your 40s, doesn't mean you can't dress fashionably, and this outfit proves exactly that.
