From over-the-top ruffles and bizarre feathers to barely-there looks and weirdly-shaped frocks, the 78th Cannes Film Festival has been filled with fashion fails.

The annual prestigious film festival – which is known for showcasing new movies from around the globe – kicked off in France on Tuesday, May 13, and will run until May 24.

And during The History Of Sound premiere on Wednesday, some wowed in glamorous dresses and stunning looks, while others completely missed the mark with their ensembles.

This included Hofit Golan, who stood out in a bold colourful embellished gown, with a dramatic matching necklace and a heart clutch bag.

Her dress featured a plunging neckline which proved to be a daring choice given the increasingly conservative outfit guidelines.

Meanwhile, Leonie Hanne hit the red carpet in a frumpy white frock with matching puff sleeves.

The day before the event began, the Cannes Film Festival released a shocking dress code for its participants.

The new rules, devised for ‘the sake of decency,’ were implemented as French director Amélie Bonnin’s Leave One Day opened the ceremony.

‘For decency reasons, nudity is prohibited on the red carpet, as well as in any other area of the festival,’ read its official rule book.

‘Voluminous outfits, in particular those with a large train, that hinder the proper flow of traffic of guests and complicate seating in the theater are not permitted.

‘The festival welcoming teams will be obligated to prohibit red carpet access to anyone not respecting these rules.’

Heidi Klum broke the dress code by wearing a ruffled pink gown that indeed had a long train that trailed behind her.

French actress and model Frederique Bel left a little too much to imagination in her cut-out gold dress, which she paired with a purse shaped like French fries.

Chinese influencer and actress Wan Qianhui arrived to the event in a dramatic, strapless, white dress containing immense fluffy ruffles.

TV personality Farhana Bodi certainly ensured all eyes were on her… but for the wrong reasons.

She walked the red carpet in a sparkly, pink dress, which contained an enormous piece of fabric that went around her head.

British actress Erin Kellyman’s white number contained a feathered neckpiece that looked like something a clown might wear. She paired the strange look with pointy boots.

This year’s Cannes Film Festival is taking place in the wake of Trump´s vow to enact tariffs on international films.

Cannes, where filmmakers, sales agents and journalists gather from around the world, is the Olympics of the big screen, with its own golden prize, the Palme d’Or, to give out at the end.

Filmmakers come from nearly every corner of the globe to showcase their films while dealmakers work through the night to sell finished films or packaged productions to various territories.

But Trump sent shock waves through Hollywood and the international film community when he announced on May 4 that all movies ‘produced in Foreign Lands’ will face 100 per cent tariffs.

The White House has said no final decisions have been made. Options being explored include federal incentives for US-based productions, rather than tariffs.

This year, some of the first-time filmmakers at Cannes are already particularly well-known.

Kristen Stewart (The Chronology of Water), Scarlett Johansson (Eleanor the Great) and Harris Dickinson (Urchin) have all unveiled their feature directorial debuts in Cannes’ Un Certain Regard sidebar section.

Many Cannes veterans have returned, including Tom Cruise (Mission: Impossible – The Final Reckoning), Robert De Niro – who received an honorary Palme d´Or 49 years after Taxi Driver premiered in Cannes – and Quentin Tarantino, who paid tribute to low-budget Western director George Sherman.

Over recent years, the star-studded extravaganza has arguably won more attention for the outfits worn by its celebrity guests than the roster of feature films being screened on the Croisette.

But new nudity rules, devised for ‘the sake of decency’, have been implemented at this year’s festival.

Halle Berry (seen at the The Phoenician Scheme red carpet on Sunday) admitted that she was forced to scrap her outfit plans following the new dress guidelines

According to organisers, the austere move is an attempt to stifle the celebrity trend for ‘naked dresses’ – namely provocative outfits that reveal considerably more than they conceal – on the red carpet.

‘For decency reasons, nudity is prohibited on the red carpet, as well as any other area of the festival,’ states a Cannes festival document.

‘The festival welcoming teams will be obligated to prohibit red carpet access to anyone not respecting these rules.’

It’s understood that the iconic venue now adopts a more conservative dress code, with suits, dinner jackets and floor-length evening gowns generally favoured over headline grabbing ensembles.

Classic little black dresses, cocktail dresses, pant-suits, dressy tops and elegant sandals, ‘with or without a heel’, will also be permitted.

While the decision to implement a more stringent policy will be a first, it is not known if French TV broadcasters, wary of airing nudity, played a role in its enforcement.

Major red carpet events, including the Cannes Film Festival, are aired in France by France Télévisions.
