KK really is an extremely versatile model. She goes from the happy-bubbly-smiley style like in her recent Elle editorial or the "LOFT by Ann Taylor" campaign, to the sexy bombshell she just did for Vogue Germany, to this much more high-fashion aesthetic. I think it's because her facial features are really very unique and definitely not "generic-commercial-model-pretty". But her personality and body and charisma are totally mainstream supermodel celebrity. So, she can lend herself to different photographic approaches very easily.
I also wish more photographers took advantage of her androgynous side, because she can be really compelling when photographed that way.
Excited to see the editorial!
