A primary goal of the newly formed corps was to be different from all the others. The concept of Latin, or Spanish style uniform was agreed upon and the corps appeared for the first time in the now familiar Caballero uniform competing in their first field competition in Trenton, New Jersey on July 20, 1947. Jim Costello's father, the late James Sr., was largely responsible for the design. He had seen a small corps in San Raphael, California with a similar uniform and thought it might work well for the Caballeros back home in New Jersey. Obviously it did.
