A double breasted blazer and white chinos are an easy way to infuse some masculine sophistication into your day-to-day casual wardrobe. A cool pair of tan tassel loafers is the simplest way to punch up this ensemble. When temps are starting to drop and fall is settling in, you'll love this getup as your favorite for summer-to-fall weather. If you're wondering what you should wear as a 30-something guy, this combo gives a fair idea.
