Make a grey sweater vest and a light blue dress shirt your outfit choice for elegant style with a modern finish. A pair of dark brown leather double monks is a never-failing footwear option here that's also full of personality. Keep this getup in your head when spring arrives, and we promise you'll save a ton of time racking your brain for an outfit on more than one morning. On the lookout for outfit ideas for 30-something gentlemen? This ensemble is pretty inspiring.
