Wear a crew-neck t-shirt with a navy fur collar coat to look refined but not too formal. Loafers will take this outfit in a dressier direction. In the winter months, when warmth is everything, it can be easy to surrender to a less-than-stylish look. However, this look proves that you can actually stay comfy and remain stylish at the same time in the winter months. In your thirties, you want to start dressing with more polish. That's when ensembles like this are a tested option.
