I don't consider Opium an old lady's perfume, it's definitely grown up and sexy, it is spicy, incensy and rich. In comparison I find Belle D'Opium rather boring but nice. If you can find it to test it out, I would test before buying. If you can find Caron Parfum Sacre, Estee Lauder Sensuous or Givenchy Organza Indecence, test those out as well. There are a few Brazilians posting here, maybe you can message them and ask for recomendations on sources to find fragrances or get samples.
