When ordering your RJ Classic's ratcatcher, please measure yourself and then order one shirt size LARGER than you measure your bust to be. This is how RJ Classics tend to fit and we want you to get the correct size!! For example if you measure a 42 order a 44.The Prestige ratcatcher features fine, imported 100% Cotton. It has a R.J. Classics horse logo on collar. Two button-closure collars come with each shirt. There is even a credit card pocket in the sleeve for your convenience as you wander the show grounds.
