Long Champ -Kate continues to be Long Champ's model this season. She looks really pretty in this campaign. This definitely beats the Long Champ SS06 campaign.
David Yurman -Kate looks gorgeous in these images. But then again, David Yurman ads always have amazing, sharp b&w images. Love this ad!
CK Jeans -Kate got famous back in the 90s because of controversial CK ads, and now she's back. She looks very cool of course, but I just think at Kate's age now, she would look cooler and classier if she had a top on, something like a denim jacket.
Belstaff -Belstaff is another brand that continues to use Kate this season. She looks so cool in the leather jacket, esp since she's got such a rock chick image. 
Stella McCartney -The nature feel of this ad is so different from the other ads. Two words sum up this ad: effortlessly cool.
