Such items as a navy blazer and black chinos are an easy way to introduce some elegance into your off-duty repertoire. A pair of black and white suede low top sneakers adds just the right amount of casualness to this look. There's no better way to spice up a gloomy fall afternoon than a cool outfit like this one. So if you need style ideas on what to wear as you age into your 40s, this getup is definitely worth saving for later.
