Well, technically, I know the “what” — it’s a Stella McCartney number. But the pants are huge, and the top looks like any number of garments from other lines that specialize in lingerie as outerwear — think Nensi Dojaka, for one. It absolutely feels like a top you’d sooner see on Emily Ratajkowski than Emily Blunt, and while I’m not trying to say she can’t experiment, I wouldn’t take it in that direction.
