I know this Document garment is a coat, but everyone in your family will refer to it as a robe. It’s okay. Just practice the whole, “Trench coats have belts. Are they robes too?!” routine and you'll be fine. It will totally stop, like, 95% of your family from saying you’re wearing a robe until the day after Christmas brunch. Your one cousin will be contrarian just to be a contrarian and say, “Yeah, I guess trench coats are robes. Looks like you and Inspector Gadget both wear robes out in public.” That’s when you tell him to go-go-gadget his dusty ass to the prime rib station to make your grandparents a plate.
