I had the Punk "Best in the World" white/black ringer T from about 13 years ago. My infant daughter had a matching onesie. Not sure what happened to that shirt though.
Now I have a "WWE Legends" 8 bit looking shirt that I was given as a bit of a gag gift a few years ago. I use that as a lounge around the house or "it's 7am at Walmart, idgaf" shirt.
As others have mentioned, 99/100 wrestling shirts have incredibly bad designs particularly on the backs. Depop tends to have some pretty obscure/vintage/bootleg shirts if anybody is searching. Oddly enough, Punk has had a few decent shirts over the years that weren't absurdly lame on the back
Oh I got a few WWE christmas tree ornaments lol. The green MITB briefcase, a microphone with the upside W logo by the Miz, and a random Macho Man gingerbread man.
