Kendall Jenner will make her first American "Vogue" appearance in the magazine's September issue. The 18-year-old reality star appears in a spread about scarves, and models a pink, paisley-print Alexander Wang scarf in the photo. The accessory is a colorful juxtaposition to her blue, paisley-print jacket and purple shirt, also by Alexander Wang. "I was thinking about Boy Scout uniforms," the designer told "Vogue" of the scarves. Jenner is a burgeoning model, and posed for the June\/July issue of "Vogue Paris." She has covered and appeared in several other magazines, and walked the runway for New York and Paris Fashion Week. Sister Kim Kardashian and her husband, Kanye West, graced the cover of U.S. "Vogue" earlier this year. "Keeping Up with the Kardashians" airs Sundays at 9 p.m. ET on the E! network.
