Take your relaxed style up a notch in a dark green shirt jacket and a short sleeve shirt. Get a bit experimental on the shoe front and complete this ensemble with a pair of black leather cowboy boots. You can bet this combination will become your go-to when cooler days are here. Gents who wonder how to sport edgy casual outfits in your thirties, this pairing should answer your question.
To put together a casual look with a twist, marry a dark green shirt jacket with a short sleeve shirt. And if you want to easily dial down this outfit with shoes, introduce navy velvet low top sneakers to your ensemble. As you can see here, this look is a really great option, especially for awkward fall weather, when the mercury is starting to drop. Overall, a good demonstration of off-duty fashion for 30-something Millennial gentlemen.
