That ain't no woman, it's a man, baby!
There is a cliche moment in many films, a morning after moment between couples, the woman is dressed in the button up shirt the man had on the night before. There are many ways to read this: symbolic submission, a symbol of their coming together as one. She on some level has crossed over INTO his world
The aesthetic narrative behind Ralph Lauren is that moment on a larger cultural scale. Ralph Lauren leverages iconography and symbolic imagery more effectively than any other fashion brand. It is a storybook narrative of a classic, eastern-seaboard America. A folklore or industrious and wealthy men who's patriarchy is so powerful that even the women's clothes seem fashioned from "his" world from things pulled from "his" drawers.
Even the poses have a masculine air. The two here on the right could be two boys, 50s greasers with cigarettes rolled up in their t-shirt sleeves standing on a street corner.
