For a look that's refined and envy-worthy, wear a navy knit turtleneck and white dress pants. Throw a pair of dark brown suede loafers in the mix to completely change up the ensemble. As the weather starts to cool down, you'll find that an outfit like this is perfect for the season. So if you're on the lookout for outfit inspo for dressing as you pass the big three-oh, this combo is a good example.
