As you can see, it doesn't take that much effort for a man to look stylish. Dress in a pea coat and a grey crew-neck t-shirt and you'll look awesome. A pair of brown leather casual boots is a good pick to complement your look. In the colder months, when functionality is above all, it can be easy to surrender to a less-than-stylish outfit in the name of convenience. This outfit, however, is a stark illustration that you can actually stay toasty and remain equally stylish during the colder months. This combination is probably what you've been looking for as a 30-something man.
