This combination of a polo and a navy trenchcoat couldn't possibly come across other than seriously dapper and effortlessly smart. Rounding off with white and blue boat shoes is the simplest way to introduce an air of stylish effortlessness to this look. This combo is a smart idea if you're crafting a knockout outfit for awkward fall weather. As you mature into your 30s, you want to start dressing like a grown-up. In this case, inspiration like this comes in very handy.
