Stewart–who is now a jury member for the prestigious film festival–previously discussed the dress code during an interview with The Hollywood Reporter in 2017.
"There's definitely a distinct dress code, right?
"People get very upset if you don't wear heels or whatever. I feel like you can't ask people that any more - it's a given. If you're not asking guys to wear heels and a dress, you cannot ask me either."
