Musician Pharrell Williams has worked with Dutch fashion brand G-Star Raw to create a denim collection made from waste plastic scooped up from the ocean.
G-Star RAW made the garments in the RAW for the Ocean collection from materials created by Bionic Yarn, which transforms recycled plastic into textiles.
"Working with G-Star was an obvious choice, because they have a legacy of pushing the boundaries of fashion and denim forward," said Williams, Bionic Yarn's creative director.
"Bionic Yarn is a company built around performance, and denim is the perfect category to show the world what Bionic Yarn can do. Everyone has jeans in their closet," he said.
Collections for men and women include jeans, shirts, coats, jumpsuits and hats all made from the recycled denim. Some of the garments are patterned with lighter-coloured designs across the fabric.
Non-denim sweatshirts and hoodies are printed with messages explaining the idea, as well as other positive slogans.
An illustrated squid has been used as the motif for the range and features on some of the items.
As well as the new range, G-Star RAW is also integrating the textiles into garments from its existing lines.
"G-Star has always been driven by innovation, and by integrating Bionic Yarn into our collection we're taking the next step in creating denim for the future," said G-Star RAW chief marketing officer Thecla Schaeffer.
The collection will be available from G-Star RAW stores and online from 15 August 2014. It was first announced at the American Museum of Natural History during New York Fashion Week in February.
G-Star RAW celebrated the 10th anniversary of its collaboration with designer Marc Newson last month, when he told Dezeen that architects and designers "don't have a clue about fashion" at the presentation of his latest range. The brand's Amsterdam headquarters, designed by OMA, was completed earlier this year.
Williams' other forays into design have included a chair with legs inspired by the caterpillar tracks on tanks.
