In my pursuit of documenting Philadelphia style, I'm often asked where do I find the most stylish people in our town. I always say 18th and Walnut streets - Rittenhouse Square - where you'll find an eclectic mix of well-dressed people. You'll see cosmopolitan couples, fashion nerds and fashion plates, and statement shoppers. New York has its 57th Street and Fifth Avenue, but Philadelphia has 18th and Walnut.
