Team an olive blazer with a cable sweater for a clean polished getup. You could perhaps get a bit experimental on the shoe front and add a pair of dark brown leather derby shoes to the equation. You can bet this getup is great when chillier weather hits. As you're maturing from your 20s to your 30s, you probably want to start dressing in a dressier manner. If that's the case, ensembles like this prove useful as a source of inspiration.
