Marrying a dark brown waistcoat with a white dress shirt is a wonderful choice for a dapper and sophisticated outfit. A pair of brown suede casual boots instantly ups the cool of your ensemble. During the colder months, when warmth is top priority, it can be easy to surrender to a less-than-stylish getup in the name of practicality. This getup, however, is a clear example that you totally can stay comfy and remain equally stylish in the colder months. If you're wondering how you should dress as a 30-something, this ensemble is a good source of inspiration.
