A double breasted blazer and a white and blue crew-neck t-shirt are great menswear must-haves that will integrate really well within your day-to-day rotation. Add black suede chelsea boots to your getup to instantly spice up the outfit. So if you're scouting for a cool outfit that will take you from winter to spring, this one fits the bill. Think 60-something gents can't pull off cool casual dressing? This combination will prove you wrong.
