"Oh, I have a few thoughts." She said, momentarily glancing past him to see a man dressed as a fork. The benefit of having known John for nearly twenty years was that she essentially had warehouses full of ammunition when it came to harassing him. There was always dressing him like Faust, that would have driven him up the wall. Or maybe one of the Beatles or someone from another band he detested. Even dressing him up like an angel or demon would annoy him enough to be entertaining. Of course, with her magic, she could have changed his shape entirely. But she didn't really want him angry, they would likely find trouble soon enough and John being in one of his moods would only bring it to them faster. And, if she were being honest, after the little trip through hell, she wasn't interested in fighting again so soon.
After taking a moment to glance around and make sure no one was paying particular attention to them, she grabbed his forearms and whispered her magic. "Emit ot yrt tuo eht wen kool." And with that his clothing began to change. Gone was his usual garb, replaced with a pair of jeans and a tee-shirt, the shirt in the style of those novelty tux tees only instead of mimicking a tux it looked more like his trenchcoat, shirt and tie.
She took a step back and looked him up and down, "Should have made the jeans tighter, regular fit doesn't suit you."
