When you need to go about your day with confidence in your outfit, consider wearing a white crew-neck t-shirt and khaki jeans. Bring a classier twist to an otherwise mostly dressed-down outfit by finishing with tobacco leather brogue boots. So as you can see, this getup is a shining example that good style and dressing smartly for winter are not mutually exclusive. If you want to portray maturity and professionalism, an outfit like this is what you're looking for.
