<p>I can’t imagine letting a boy go to boarding school interviews in a polo shirt, but I admit to being old school about this. It’s more about my own views of what’s “appropriate” than about any real sense that an AO would reject a kid for being too casual. I often make my DS put on a polo shirt to go out for dinner at any restaurant fancier than our neighborhood burger place, so that’s where I’m coming from.</p>
