Oscar producer Laura Ziskin meant well when she asked for some sort of display on stage of nominated costume designs. But what the hell was that? “Curse of the Golden Flower” and “Marie Antoinette” were showcased nicely, but the corgi next to the multiple versions of “The Queen,” the two white-haired Mirandas in their “Prada” wear and the Voguish posing of the “Dreamgirls” were just campy gone weird.
