This laid-back combo of a charcoal denim shirt and a crew-neck t-shirt is a fail-safe option when you need to look nice but have no time. For maximum fashion effect, complement your ensemble with a pair of dark brown suede casual boots. As you can see, this combo is a shining example that good style and dressing smartly for the winter months are not mutually exclusive. A nice, less conservative combo for 30-something gentlemen.
