Somehow, I've never found traditionally beautiful girls like Aishwarya and Audrey Hepburn and Grace Kelly and Catherine Denueve to be sexy unlike someone like say Monroe or Jolie or Bardot or Ursula or Sophia Loren or Zeenat Aman or Adriana Lima or Lara Stone. I think sexiness demands an edge and unconventionality, something that veers the aesthetic entirely away from the realm of beauty and shepherds it towards the more earthy, more sensual, more carnal and in your face domain of femininity. It's something innate; Sherlyn Chopra and Mallika Sherawat may bust a gut by pulling orgasmic faces and wearing scanty or no clothes, but they will always be pathetic wannabes.
