Gosh! Kendall Jenner Shows Tits In Marc Jacobs Show At New York Fashion Week

Well, am not being judgmental but simply being rational in my thinking! How can a girl of Kendall Jenner's age (18 years old) wear a risque see through outfit that basically showed her tits to the entire world?
She was a model at the Marc Jacobs show at the ongoing New York Fashion Week.
Her elder sister, Kim Kardashian went on instagram, saying she is proud of Kendall Jenner.... Huh? Proud of nudity and exploitation? Well that's more like her and the Kardashian Clans
You be the judge! Is this outfit appropriate for 18 years old?
