“When you start to lose your hair, it’s time to let it all go,” jokes Darryl Settles. Besides, a shaved head makes for easy grooming. With a little Vaseline rubbed in, he’s set for the day. Several years ago, Settles was introduced to Nova International, a Bangkok company that sends tailors to Boston several times a year to measure and make custom clothing for businessmen. He likes being able to select fabrics, as for this textured dress shirt.
