A navy denim jacket and dark green cargo pants are a cool combination that will carry you throughout the day. If you wish to easily dial up this ensemble with one single piece, why not add a pair of brown suede loafers to the equation? There's nothing like a kick-ass combination to spice up a dull autumn afternoon. As you turn 30, you want to start dressing more maturely. If that's the case, ensembles like this are a never-failing option.
