This combo of a white blazer and beige dress pants is a foolproof option when you need to look like a menswear guru. You can get a bit experimental in the footwear department and dress down this outfit with brown suede casual boots. When it comes to dressing for transitional weather, nothing beats a cool getup that can take you from season to season. So if you need fashion inspiration for dressing as you reach your 40s, this pairing is definitely worth saving for later.
