But don't worry she's not going to be sending plastic skirts, shirts and jackets down the runway anytime soon, McCartney is fashion-forward but she's also realistic. Her new partnership is with Parley for the Oceans - a company whose primary mission according to their website is "...to save as many (marine) animals as possible," and one way they're working towards this is by producing yarn made from recycled plastic debris collected from the oceans.

The organisation says recent research pegs the amount of plastic garbage at over 40 million pounds in the North Pacific Ocean alone, and that doesn't even take into account any of our other oceans. A report by the Ellen MacArthur Foundation released last year and reported in The Guardian said each year, "atleast 8m tonnes of plastics leak into the ocean - which is equivalent to dumping the contents of one garbage truck into the ocean every minute."

The Parley for the Oceans yarn McCartney will include in her garments is made from discarded plastic objects like fishing nets, plastic bottles and other debris, which is then woven into a fine yarn. Parley for the Oceans also turns the plastic into polymers for the beauty industry and raw materials for use in the packaging and construction industry.

McCartney's brand is a "vegan" luxury fashion brand which disrupted the fashion industry when she first started out, her no leather or animal inputs stance shocking the industry who considered leather and fur essential for a luxury fashion label. As one of the most popular and coveted brands, McCartney has firmly proved naysayers wrong. Speaking about the new partnership to The New Yorks Times she said, "To take something that is destructive and turn it into something that's sexy and cool, how can than not be luxury?"
