An evening at the Cannes Film Festival means lots of flashbulbs and even more exciting looks for the guests. Enter Amal Clooney, confidently in the spotlight. This time, she wasn’t accompanied by husband George Clooney, but made a solo appearance that radiated self-assurance. If anyone knows how to deliver a fashion statement, it’s the human rights lawyer. And that’s exactly what she did – with a dress that was as exciting as it was elegant – but also violated the new strict dress code.

Amal Clooney stuns in vintage dress at the 2025 Cannes Film Festival

Amal Clooney appeared at the 78th Cannes Film Festival in a stunning vintage mermaid dress by John Galliano. The floor-length gown in deep black is a vintage design from the Galliano era for the fashion house Christian Dior. The classic mermaid silhouette, long train and off-shoulder neckline were definitely eye-catching – a look on the red carpet that promises glamor and delivers it.

The outfit was completed with a simple black clutch and long diamond earrings, which added extra glamour to the already sophisticated look without overpowering it. Her jewellery remained deliberately understated but appeared carefully selected — a sign of Amal Clooney’s refined sense of balance between understatement and statement.

The new dress code at the Cannes Film Festival: Is Amal Clooney breaking the controversial dress code?

The human rights lawyer and well-known philanthropist stayed true to her unmistakable style: glamorous, vintage-loving, and elegant. Yet her look sparked not just admiration but also debate. That’s because the Cannes Film Festival has recently introduced a stricter dress code: overly daring or extravagant looks — like sheer fabrics or voluminous trains — are no longer welcome and, at worst, could lead to a ban from the red carpet.
