Who's the famous, married, narcissistic female fashion designer known as the "Baroness" who "enjoys torturing and humiliating her underlings... In her mind, she's happy, her victims are grateful, and she is their 'beacon.'" [NY Times]

Update: A reader says, "The Baroness isn't really a famous celebrity fashion designer like DVF or Donatella Versace (unless you mean by fetish standards). Her designer name is the Baroness, her website is www.baroness.com, and she has a store in the East Village where she sells her latex clothing."
