Stella McCartney chose Kate Moss and Kaia Gerber to represent her eponymous brand because the two models represent the "wonder of women" across the generations.
The 47-year-old designer recently unveiled her latest collection at her spring/summer 2019 show and she selected 44-year-old supermodel Kate to represent "women of today" and 17-year-old rising star Kaia - whose mother is catwalk legend Cindy Crawford - to symbolise "women of tomorrow".
Speaking to Vogue UK, she said: "I have a true connection with these women. For this season, I wanted to capture the wonder of women: the circle of life and the love of learning from those that inspire and came before us and are in the now. We represent women of any age."
This will be supermodel Kate's seventh time posing as the face of the label and Kaia's first campaign, and the designer insists both models "bold beauty" shone through during the shoot.
Stella - whose father is Beatles legend Sir Paul McCartney - said: "There was so much energy at the shoot! Kate and Kaia's bold beauty really shine in these images ... and our effortless relationships - how we choose to support one another over time - come through."
A lot of Stella's latest collection is made using environmentally friendly materials, including regenerated cashmere, organic cotton and denim, recycled nylon and sustainable viscose, and a favourite of the designer includes the new monogram cluster bags, which are made from environmentally-friendly cotton.
