Go for a black double breasted blazer and sweatpants if you're aiming for a crisp, on-trend ensemble. Dial up the fashion factor of your ensemble by sporting white and black low top sneakers. Perfect if you're on a mission for some amazingly inspiring off-duty style for over-30 gentlemen.
For a casually dapper outfit, consider teaming a blue denim jacket with sweatpants — these items work really well together. A pair of white and black low top sneakers is a nice idea to complete your getup. A fail-safe option combination appropriate for guys in their 30s who like casual dressing.
