So as you can see, it doesn't require that much effort for a man to look sharp. Just pair a blue blazer with a light blue long sleeve shirt and be sure you'll look incredibly stylish. When it comes to shoes, this ensemble pairs really well with tobacco leather casual boots. During the winter months, when practicality is essential, it can be easy to surrender to a less-than-stylish outfit in the name of functionality. But this outfit is a bright example that you can actually stay cozy and remain equally stylish during the winter months. A look like this can make any gentleman in his thirties look better than any of his peers.
