This laid-back combination of a grey wool turtleneck and dark green corduroy chinos is a real life saver when you need to look nice but have zero time to plan an ensemble. Introduce black suede desert boots to this getup and ta-da: the look is complete. As you head into your 30s, you probably want to start dressing more maturely. If that's the case, combinations like this are a never-failing option.
