"Do Not Pet" t-shirts?

[Maxy24]

Has anyone ever bought their dog any sort of clothing that tells people not to pet them? I sort of want to buy Tucker something for those occasions when people try to pet without asking first. I can find them from plenty of places but I'm always nervous about buying anything online and having it not fit right or be super low quality. Especially the shirts that have arms sticking out of the side instead of the bottom, that really bugs me, that's not where his arms go lol.
So I was just wondering if anyone had gotten them before and know of a good place with well fitting shirts. I want it to be easy to read without staring at the dog for several seconds (since he wouldn't like that very much) and don't want it to say he's in training or anything, just a simple do not pet or fearful do not pet message.
