The pressure is on when you’re co-hosting the Met Gala, but of course Dua Lipa delivered. The pop star arrived on the red carpet in a white tweed gown from Chanel’s Fall/Winter 1992 Haute Couture collection. But the dress, first worn on the runway by Lagerfeld muse Claudia Schiffer, wasn’t the only showstopping aspect of her look. There were also the accessories: namely, a massive, more than 100-carat, one-of-a-kind Tiffany & Co. diamond necklace.
