So for Sonam, who does she think has made the most impressive appearance on Cannes so far?
“I love Vidya Balan and I thought she did an amazing job with the way she dressed up last year. She was incredible,” said Sonam who also finds India one of the most “extremely stylish country”.
“Nothing is more stylish and sexier than an Indian sari and nothing is more elegant than angrakha and nothing looks better than sherwani,” she said.
