This pairing of a tan zip neck sweater and a dress shirt is ideal when you need to look sharp but have zero time to spare. Finishing with dark brown leather desert boots is an easy way to inject a laid-back touch into this outfit. So as you can see, this combo is a really nice option, especially for unpredictable fall weather, when the temperature is falling. A solid pairing as you transition into the next stage of your life, your 30s.
