A dark green suit looks so elegant when matched with a grey overcoat in a modern man's look. Take your outfit in a less formal direction by finishing with tobacco leather monks. A vivid example for any gentleman who's not sure how to dress like an adult.
Tobacco Leather Monks with Dark Green Suit Cold Weather Outfits In Their 30s
We love how this combination of a dark green suit and a brown plaid overcoat instantly makes men look dapper and elegant. On the shoe front, this outfit is complemented really well with tobacco leather monks. This ensemble is most probably exactly what you've been looking for as a guy in his 30s.
