Femme, we are told, was thus constructed around this plum note, enriched with oakmoss and peach. It is of interest to note that the lineage existing between another Guerlain perfume and Femme is rather obvious on the empirical intuitive level even if you do not know that both contain the peachy Gamma-Undecalactone or Aldehyde C-14 and that is the kinship existing between Femme (1943-1945) and Mitsouko (1919), both being lush fruity chypres with a stewed-fruit quality to them.
