A black field jacket and a navy chambray long sleeve shirt are stylish menswear pieces, without which our closets would definitely feel incomplete. You could perhaps get a little creative on the shoe front and dial down this outfit by finishing off with brown leather work boots. Can you see how extremely easy it is to look sharp and stay comfy when fall arrives, thanks to this ensemble? Overall, a good demonstration of laid-back fashion for 30-year-old gentlemen.
