Emma Watson shined on the red, actually green, carpet for the first time in a while wearing a unique, eco-chic ensemble.
While attending Earthshot Prize ceremony, the "Little Woman" actress was photographed wearing a white tulle-style asymmetrical dress and black wide-leg trousers.
Her hard-to-miss look was an upcycled demi-couture gown designed by gender-fluid fashion label Harris Reed. To create the look, old wedding dresses donated from Oxfam GB, a British founded confederation of 20 independent charitable organizations focused on alleviating poverty, were used.
"I had the immense honour to dress Emma Watson in customized head-to-toe Harris Reed for tonight's Earthshot Prize," Reed said in a post.
The designer also sent a "massive massive" thank you to the team that helped him bring the look to life.
Watson was not only an attendee but also a presenter for the inaugural affair.
This hasn't been her first time advocating for sustainable fashion. In 2016, the actress wore a stunning gown made from recycled plastic bottles in collaboration with Calvin Klein.
The London-based ceremony was hosted by Duchess Kate and the Royal Foundation and honors several notables who have tackled challenges as they relate to climate change.
Other standout attendees included Ed Sheeran and Emma Thompson.
Like Watson, The Duchess of Cambridge, also wore a recycled Alexander McQueen dress that she first was seen wearing for the 2011 BAFTAs in Los Angeles.
Accompanying her, Prince William wore a black turtleneck and velvet green blazer.
