Cate Blanchett just re-wore her 2014 Golden Globes dress for a very important reason

And we love her even more for it.

The Cannes Film Festival opened this week, with swarms of A-List celebrities taking to the red carpet on the French Riviera, to celebrate the 71st annual event’s opening night.

Julianne Moore took to the selfie-free red carpet in a caped red Givenchy gown while Chloe Sevigny opted for Chanel Couture, with some even making a political statement with their dress choice, with Penelope Cruz, Kristen Stewart and Georgia May Jagger all donning black for the occasion - a nod to the Time’s Up movement and its stand against the mistreatment of women.

The A-list actress who made the most waves in black was Cannes jury president Cate Blanchett, but it wasn’t the colour palette that got the world talking, but more the dress itself.

The 48-year-old Academy award winner took to the red carpet in a black lace crinoline Giorgio Armani Privé gown.

Recognise it? You might well do, as Cate has worn this exact look before at a high profile event, recycling her iconic dress from the 2014 Golden Globes where she won an award for her performance in Blue Jasmine.

When asked if the recycling of the couture gown was intentional, Cate confirmed that it was, explaining her meaningful reason behind the decision.

‘From couture to t-shirts, landfill is full of garments that have been unnecessarily discarded,’ she explained to InStyle. ‘Particularly in today’s climate, it seems willful and ridiculous that such garments are not cherished and re-worn for a lifetime.’

This was confirmed by her stylist Elizabeth Stewart, who took the moment to champion recycling outfits in an interview with Eco-Age.

‘I think the stigma around re-wearing a dress is arbitrary and makes no sense,’ she explained. ‘It's a rule that will fade away like the “no white after Labour Day” rule. We don't visit the Louvre expecting a new masterpiece each time. True beauty and art endures.’

Yet another reason to love Cate Blanchett - like we needed one!
