If you wish to easily up the ante of your outfit with one piece, introduce a pair of black casual boots to the mix. When spring is in the air, you'll appreciate how great this ensemble is for transitional weather. Those who are curious whether you can still pull off cool casual style as you head into your 50s, you have your answer.
