As you can see, it doesn't require that much effort for a man to look casually classy. Consider pairing a brown blazer with jeans and you'll look incredibly stylish. You could perhaps get a bit experimental when it comes to footwear and complete this ensemble with a pair of dark brown suede tassel loafers. So if you need fashion inspo for dressing as you step into your 40s, this getup is a perfect example.
