Unfortunatly you can't just throw it away and say you must have misplaced it. If he likes it, it's there to stay. HOWEVER, I suggest buying him another jacket that you like, and something he would wear, to cut down on the...white...thing. At least he could alternate days with the two, and down the road maybe a third, and so on. It's a slow process, but sooner or later cherry Kool-Aid is bound to spill on it.
