Willow's body language is interesting to watch. It falls somewhere between unawareness and control. She uses her body like a dancer, or an athlete. I'd not call this a fashion editorial: the clothes are a non-entity, they are there just so she's not naked, they serve no purpose beyond that. Since Willow's physique has more plasticity than the average actor/musician/celebrity, Kudacki zeroes in on movement, not pose, which is a smart choice, just questionable for a magazine like Elle France.
I understand, however, that there is no other way to address the subject. Willow you want, Willow you get. And to judge from the cringey "Vos ados l'adorent!" on the cover, one-dimensional, fast-celeb Willow is exactly what Elle France wanted in the first place.
