The piping on the collar, cuff, and hem adds an elegant touch. I have the ivory and navy blue and white polka-dot co-ords, but the other pigmented shades, such as black, olive green, and navy, have more noticeable piping. Also, while I adore a matching set, Cozy Earth also allows you to mix and match hues for the top and bottom, so go ahead and live out your most colorful dreams.
