For an outfit that's pared-down but can be smartened up or dressed down in many different ways, consider teaming a white crew-neck t-shirt with black dress pants. Finishing off with a pair of white and blue canvas low top sneakers is a simple way to bring a dash of stylish casualness to your ensemble. As a 30-year-old guy, you want to start dressing more professionally. In this case, combos like this become a great source of inspiration.
