Ralph Lauren Fall/Winter 2015American design royalty Ralph Lauren headlined the last day of New York Fashion Week on Thursday with brown and gray elegance in cashmere and shearling, and menswear-inspired tuxedo suiting for evening. Rapper Kanye West was the self-invited guest of honor, mobbed by photographers as he took his seat to watch the study in classic American beauty — while dressed in cargo pants and a bomber jacket, and chewing gum.
