> – The actress, then 21, later joked the incident became “the talk of the festival”
> – Why it matters: Fanning’s candid retelling highlights the physical toll of red-carpet fashion and keeps the spotlight on health over style
The Cannes Film Festival is known for glamorous gowns and cinematic buzz, but in 2019 juror Elle Fanning gave the crowd something else to discuss when she collapsed at a Chopard dinner.
The Fainting Incident
While Festival director Thierry Fremaux was introducing actor Francois Civil, Fanning’s vintage 1950s Prada prom dress-adorned with red, pink and blue flowers-proved too constricting. She slid off her chair mid-ceremony.
Fanning told W Magazine:
> “Yes, my dress was too tight. My sister saw my chair fall back. It’s kind of hilarious-very dramatic.”
Colin Firth rushed to help, and the moment quickly circled the festival.
What Led to the Collapse
Beyond the snug fit, Fanning cited her history of fainting:
- Grew seven inches in a single school year, triggering altitude-sickness-like symptoms
- Frequently passed out during class
- Added that it was also her “#timeofthemonth”
She later posted a smiling selfie captioned:
> “Oops, had a fainting spell tonight in my 1950’s Prada prom dress but it’s all good.”
Support poured in, with January Jones commenting:
> “Where’s your smelling salts when you need em??”
Fanning simply replied, “Amen!”
No Fashion Regrets-Except One Hairstyle
The actress maintains she has no clothing regrets, but she draws the line at faux bangs:
> “Being a blonde, it’s hard to match my hair color, and it looked like a big toupee. I won’t be doing that again.”

Key Takeaways
- Fanning’s 2019 Cannes collapse was caused by a too-tight gown and her tendency to faint
- The incident drew attention to health over fashion on cinema’s biggest stage
- Despite the scare, Fanning keeps her humor intact and refuses to dwell on style missteps
Her retelling is a reminder that even A-list glamour can’t override basic biology.
