Could a show have left a happier or more uplifted crowd than did the one put on by Mr. Isaac Mizrahi yesterday afternoon? What did we do without him showing under the tents all this time? Why send the models in a straight line when they can navigate a charming obstacle course that encompasses a staircase, rain shower, and diagonals? Is there a better way to be transported to Deauville in the ’20s? What magnificent musicians performed that jazzy original composition right there beside us? Will a boater look as good on us? Does Isaac want to be friends? Is that spun-fabric flower real? Would they know if we stole that purple dress? Was the man with the umbrella drunk?
