Elle Fanning, the newly-minted unofficial princess of Cannes, may have taken her commitment to fashion too far when she had a minor health scare - likely due to her dress's tight corset.

The 21-year-old actress collapsed at the Chopard Trophee dinner on Monday evening at Cannes.

Fanning shared a photo of herself giving a thumbs up for the camera.

"Oops, had a fainting spell tonight in my 1950's Prada prom dress but it's all good!" she wrote, adding "#dresstootight". Her dress featured a corseted waist, which may have been the cause of the unconsciousness.

Former Mad Men stars January Jones and Kiernan Shipka were among those to comment on the post. Civil had just been introduced on stage when Fanning fell out of her chair, Variety reports.

Fanning is on the jury in Cannes.

Actor Colin Firth also reportedly offered his assistance to the "Maleficent" actress, as he was seated near her at the event, according to the publication.

Fanning's sister, actress Dakota Fanning, helped the star to her feet before security ushered them out.

The "Super 8" star later took to her Instagram to let fans know that she was okay and she blamed the whole ordeal of her dress being "too tight".
