Okay, technically it’s not a gown — it’s a vintage Givenchy pantsuit, complete with authentic red-wine stain, which Coco Rocha wore to the Met Ball after purchasing it from an auction of Elizabeth Taylor’s things. Had Coco worn it, say, to a movie premiere or to a party honoring some random new smartphone, we might feel differently. But this outfit has two places in time: on Elizabeth in its era, and on Rocha here, as a nod to the “Impossible Conversation” between a deceased superstar and a living supermodel. We loved it as a clever nod to the night’s theme, and Coco wore the hell out of it — no mean feat when you try to imagine if Lindsay Lohan, in full Taylor regalia, had worn it in Liz & Dick. We are clutching our phantom pearls in very real horror.
