Never a big Janis Joplin fan, though I do love her version of "oh, Lord, won't you buy me a Mercedes Benz".
Miss Dior was my very first grown up, real (expensive) perfume - as opposed to Tweed or Tabu or Freesia by Yardley - but it's unrecognisable now from the sophisticated original, really much too sweet like most perfumes today...Thierry Mugler's Angel has a lot to answer for!
As for the bit in the ad where she says "and you? What would you do for love?" to me, she just looks gormless. Very beautiful but gormless.
