This laid-back combo of a teal shirt jacket and blue jeans is ideal when you want to feel confident in your ensemble. For something more on the cool and laid-back end to finish this outfit, slip into a pair of grey athletic shoes. As you can see, this look is a bright example that good style and dressing warmly for the winter season are not mutually exclusive. Overall, an ideal demonstration of off-duty fashion for guys in their 30s.
