The problem is that she is still pushing for fame and success using her family name… just in a different way. Fashion instead of reality TV. And if she wasn't a Kardashian, she would never be where she is now- no Cannes, no Vogue, no Met Gala, nothing. Had she had the same opportunities as majority of models, she would never even be seen anywhere near a runway.
She might be more stylish and elegant than the rest of her family, but truthfully, it is not a difficult feat to achieve. She appears to be an example of a kid who heard her whole life: "oh, you're such a tall pretty girl, you should model", and decided to go for it (after all modeling does seem glamorous, and another way to stay in the spotlight and live the fun life, while appearing to be working).
I can't blame her for doing what she's doing, but she should just choose: either being a celebrity and using her family name to get things (not a bad option), or if she wants to seriously achieve anything for herself, she should just drop the weight and really try to have some success on her own.
Right now she's trying to do both, and it's not working.
