This pairing of a light blue long sleeve shirt and charcoal chinos combines comfort and utility and helps keep it low profile yet trendy. For a classier feel, why not complement this look with brown leather casual boots? In the colder months, when comfort is imperative, it can be easy to surrender to a less-than-stylish getup in the name of practicality. However, this getup is a clear example that you totally can stay cozy and remain stylish at the same time during the colder months. As a man in his 30s, you probably want to start dressing maturely. That's when inspiration like this is very useful.
