So as you can see, it doesn't take that much work for a man to look stylish. Team a dark brown shirt jacket with a brown turtleneck and be sure you'll look incredibly stylish. Complete your look with a pair of beige suede desert boots and you're all set looking awesome. So if you're after a look that's dapper but also entirely spring-friendly, this one fits the task well. If you're wondering what you should wear as a gentleman in his thirties, this outfit is a good source of inspiration.
