Showcase that you do smart casual men's style like no-one else in a white dress shirt and charcoal corduroy chinos. If you wish to immediately amp up this outfit with one piece, introduce a pair of navy suede oxford shoes to this getup. So when summer is fading away and autumn is taking over, this getup is likely to become your favorite. That's the look for a 30-year-old man to project he has what it takes to succeed.
