This look with a dark green overcoat and navy jeans isn't super hard to pull together and leaves room to more creative experimentation. Bring a dash of class to your ensemble by finishing off with derby shoes. This one is an excellent pick when it comes to a neat summer-to-fall ensemble. You can take cues from combos like this if you've passed the big 3-0 and you want to take a more mature approach to your personal style.
