Effortlessly blurring the line between dapper and casual, this combo of a navy and white floral short sleeve shirt and white jeans will likely become one of your favorites. A pair of white athletic shoes can immediately dial down a dressy outfit. As you can see, this ensemble is a really wonderful pick, especially for unpredictable fall weather, when the temps are getting lower. Those who wonder whether you can still sport cool off-duty outfits as you step into your 40s, you have your answer.
