In WCW, referees wore collared shirts with bow ties until around 1999, when they switched to striped shirts. During The Invasion storyline in WWE (known at the time as WWF), the WCW referees wore white polo shirts, switching near the end of the storyline to baseball-jersey style grey shirts with a small black WCW logo on the left breast and one on the right sleeve. In ECW, referees first wore striped shirts (as they split off from the NWA), and later wore an all-black uniform akin to those of mixed martial arts officials, later with a half-black, half-red shirt. The all black uniform would return for the first two WWE One Night Stand events, before giving way to the brand extension ECW referee shirts.
