WWE referees have had a series of different uniforms throughout the years. From the 1970s until 1983, still operating under the World Wide Wrestling Federation banner, referees wore black and white striped shirts, comparable to referees in other sports, such as ice hockey, basketball, and American football. In the mid-1980s until 1995, a World Wrestling Federation (WWF) referee's attire consisted of a blue collared shirt with black trousers, boots, and bow tie, similar to that of a boxing official. Beginning with the March 13, 1995 episode of "Monday Night Raw", the uniform was changed back to the black and white striped shirt with a WWF logo patch on the left breast as well as the shoulders. With the WWE brand extension in 2002, referees appearing on "SmackDown!" began wearing blue polo shirts with black pinstripes, differentiating themselves from the Raw referees, who continued to wear black and white shirts. When ECW was revived in 2006, their referees were given black shirts. As of 2007, they had grey and black polo shirts. As of November 2008, however, all referees wore black and white striped shirts and were no longer brand exclusive. On the November 15, 2010 episode of "Raw", the referees wore the "boxing referee" attire as part of the "Old School Raw" special episode. Since the re-establishment of the brand extension in 2016, WWE referees have given colored designations on the patches with the logo; for instance, blue for SmackDown and red for Raw.
