Only Natalia Vodianova Can Sit Like This And Still Look Lovely

Looking slightly off-guard on film, is Natalia Vodianova surprised she landed another Stella McCartney campaign? Nope, that's not quite the case for the seasoned model (or her doe eyes) who stars in the summer '13 ads. The just-released shots follow in a string of McCartney/Vodianova collaborations (because if it ain't broke, don't fix it) that also include the behind-the-scenes talents of shutterbugs Mert Alas and Marcus Piggott.

Appearing contorted, shocked, and maybe even a bit perturbed, the model brings humor and lightness to the line of clothes that, in essence, are made to make us feel good. Plus, along with the inspiration to slip into a monochromatic, eyelet number, the images also introduce the Bailey Boo: McCartney's new edition to her line of ethically made fashion.
