Jeremy's Bulldog Shirt
Jez’s t-shirt, here, is made by Firetrap. There’s not a whole lot of stores that still carry this style, but we found one French online retailer which seems to still have some of these in stock. The only issue with that is that their site is all in French, with no option for English. Good luck!
