The show shirt, called a "ratcatcher," is a buttoned shirt with a stand-up mandarin-style collar covered by a separate, matching choker or a stock tie, the final look usually resembling that of a turtleneck. The traditional, classic shirt is white. However, in some places and at some types of less formal competition, particularly for children, pastel-colored shirts are popular, coordinated with the colors in the hunt coat. Traditionally shirts were long-sleeved, but today are more often short-sleeved or sleeveless, though sleeveless shirts cannot be worn when the jacket rule is waived. Stock pins are sometimes worn on the stock tie or choker, although the most recent fashion has been to embroider the rider's initials on the choker.
