Autumn ad campaigns continue to roll out and this time it's Stella McCartney's turn. She has recruited model friend Natalia Vodianova to front her advertising as she poses in key pieces like a chunky cardigan, statement LRD and tailored coat. The images have playful, child like font across them which is sure to create mixed feelings (or just confuse you). This is a second season for Natalia who also appeared in the Spring campaign. What do you think of these playful-but-serious images?
