Why not consider wearing a dark green short sleeve shirt and black chinos? As well as very comfortable, both of these pieces look great when paired together. Finishing off with a pair of work boots is a fail-safe way to bring an easy-going touch to your outfit. So if you're on the lookout for an outfit that's dapper but also feels totally spring-friendly, this one fits the task well. Relaxed getups for stylish gentlemen in their 30s aren't actually that hard, as you see.
