If you use a more casual approach to dressing up, why not rock a crew-neck t-shirt with blue chinos? If you want to instantly dress down this look with one single item, complement your look with charcoal work boots. When you're having one of those dull fall days, sometimes only a kick-ass getup like this one can get you out the door in the morning. This getup illustrates that well into your 30s you have a wide range of sartorial options.
