The perfect choice for a neat and casually polished getup? A crew-neck t-shirt with a navy fur collar coat. And if you wish to easily rev up your getup with a pair of shoes, add a pair of tassel loafers to your ensemble. So as you can see, this combo is a shining example that good style and dressing smartly for the colder months are not mutually exclusive. This is a stylish yet age-appropriate ensemble for 30-year-old men.
