We're loving how this pairing of a black wool blazer and navy wool dress pants immediately makes men look sharp and classy. If you want to break out of the mold a little, add a pair of dark brown suede desert boots to the mix. Keep this ensemble in mind come warmer days, and rest assured, you'll save a lot of time racking your brain for what to wear on more than one occasion. Wondering how to dress after thirty? This ensemble is a perfect example.
