Natalia Vodianova and Mariacarla Boscono are the faces of Stella McCartney's spring/summer ad campaign.
The first image released on Instagram shows the long and lithe supermodels lying on the grass and clasping hands, garbed in crimson and flush pink body-skimming knit dresses.
"I wanted to evoke the laidback feeling of summer; a celebration of love and friendship. The images have a sense of lightness, an open heart with an edge to it," writes McCartney.
The campaign was photographed by Harley Weir outside Paris.
Wild horses figure prominently in the new collection, as a motif for black and white dresses, blouses and sweatshirts.
The collection also includes crisp suits, pleats and statement bow-tie details.
