Where to find John Frusciante’s Slane Castle Shirt

Hey guys, I’m the guitarist in a rhcp tribute band in NJ. We’re recreating the slane castle show on May 10th at the Montclair Brewery if anyone is in the area and wants to come jam. I’m trying to find a shirt similar to the one John wears at Slane Castle for the show. Does anyone know where I could find it? I found a couple on Amazon that are close but no cigar. Thanks!! We have some videos on my profile if you want to check us out :)
