Why not go for an olive gilet and black jeans? As well as totally comfortable, these pieces look good when combined together. If you're clueless about how to finish, a pair of low top sneakers is a nice pick. So as you can see, it's a stylish, not to mention spring-ready, ensemble to keep in your transeasonal rotation. No doubt, a nice pick if we're talking dressing ideas for men in their 30s.
