1. nWo
The top spot is taken by a shirt that is not produced by Titan Sports or World Wrestling Entertainment. As good as many of the WWE shirts have been, this t-shirt was better than anything they ever produced. This shirt started a revolution in the wrestling world. The original nWo shirt was one of the most popular shirts of all time and can still be seen today by fans all over the wrestling world. The shirt has come to represent many superstars, but most notably the original trio of Hollywood Hogan, Kevin Nash, and Scott Hall. While WCW was never known for its marketing genius, they nailed this shirt design. The black and white logo is simple yet says so much and was undoubtedly the best-selling WCW shirt of all time. Unfortunately, the WCW was not producing enough of these shirts at the onset and left tons of money on the table. Scott Hall has spoken in interviews about fans asking him for his shirt and when he would respond, "Go buy one," their reaction was that the concession stands were all sold out. While that type of snafu is hopefully a one-off as far as mistakes go, that was something unlikely to ever happen in the company ran by Vince McMahon. Regardless of its limited availability during the genesis of the nWo, the shirt has stood the test of time as the greatest wrestling t-shirt ever.
