That one is a rip-off (or nostalgie?) from s/s 2001 collection: full of chains. Karolina Kurkova taken by Sean Ellis was in that campaign. Prove
Again: Leather+ chains
I`ve Got that one which Karolina worn here
I don`t think Julia is the right model`s choice for this: she doesn`t have hips and pants looks shapeless on her. And supposed to look "cutie" pigeon toes aren`t appropriate to the image with snakeskin leather pants...
Hedi Slimane? Sure thing, not, but it looks pretty much his work (minimalism, black tuxedo, jacket worn on naked breast)
this is just creppy and stands out of the campaign
