Primates of Pacific Heights - San Francisco Chronicle (subscription)

In the book "Primates of Park Avenue," by Wednesday Martin, the author uses anthropology to explain the tribal practices of mothers in the Upper East Side of New York, including their dress codes and which accessories carry the most status. The Birkin bag by Hermes is considered one of the most coveted handbags, starting at $8,000 for plain leather bag and running up to $150,000 or more for bags in crocodile or ostrich skin.
