A person called Chadwick John Dillon produced this suit-of-armor hoodie. He's apparently selling it (or possibly producing them to order). The details require a Facebook account, which I don't have. Chadwick, if you're reading this, consider me interested (though not interested enough to give Mark Zuckerberg all the intimate details of my life!).
Update: From the comments, Melissa Gutierrez sez, "The maker has an Etsy shop that is in vacation mode at the moment because of overwhelming interest in said hoodie."
