A red field jacket and white jeans are bona fide menswear must-haves if you're figuring out a casual wardrobe that matches up to the highest sartorial standards. For something more on the classier end to round off this ensemble, introduce a pair of brown leather tassel loafers to your ensemble. So as you can see, it's a dapper, not to mention spring-friendly, getup to have in your transeasonal collection. Looking for fashion for guys in their forties? This combo is pretty inspiring.
