You'll be surprised at how extremely easy it is for any gentleman to throw together this casually sleek outfit. Just a dark green sweater vest and a navy and white vertical striped long sleeve shirt. Make black chunky leather derby shoes your footwear choice for a masculine aesthetic. As you can see here, this combination is a really nice pick, especially for in-between weather, when the mercury is dropping. Also, it's a wonderful ensemble to fit in with a professional crowd.
