The sari, in essence, is a six- to nine-yard cloth draped freely around the body. In April, Zendaya wore a sparkling deep-blue sari by Rahul Mishra on a red carpet in Mumbai, India. At the 2022 Cannes Film Festival, the Indian actress Deepika Padukone wore a shimmering gold-and-black sari by Sabyasachi Mukherjee that Vogue France called “the star piece” of the festival. Ms. Poonawalla’s Met Gala sari is among the pieces featured in a new exhibition, “The Offbeat Sari,” opening on Friday at the Design Museum in London. The show, which runs through September, explores how the sari is being newly defined, said Priya Khanchandani, the head of curatorial at the museum.
