A suit and a brown turtleneck teamed together are a savvy match. Amp up your whole ensemble by finishing off with dark brown suede brogue boots. During winter, when warmth is a must, it can be easy to settle for a less-than-stylish ensemble in the name of convenience. But this ensemble proves that you can actually stay toasty and remain equally stylish in winter. As a 30-something man, you probably want to start dressing more maturely. In this case, combinations like this are a never-failing option.
