A navy plaid blazer and beige chinos are the ideal way to introduce a dose of manly sophistication into your current casual routine. Introduce a pair of tobacco leather derby shoes to the equation to easily boost the wow factor of any ensemble. When temps are starting to drop and autumn is setting in, you'll appreciate how ideal this ensemble is for unpredictable fall weather. This combination shows that dressing cool as a 30-year-old gent is not that hard.
