A light blue denim jacket and black jeans are absolute essentials if you're planning an off-duty closet that matches up to the highest menswear standards. Complement this ensemble with a pair of white leather low top sneakers and ta-da: the ensemble is complete. A cool ensemble that transitions easily into fall like this one makes it very easy to welcome the new season. Perfect for a man in his 20s if you want to project a mellow image.
