At the moment my GF uses D&G The One, Gaultierīs Ma Dame, Armani Diamonds, Hypnotic&Midnight Poison and YSL Elle (Iīm sure Iīve forgotten some) and most of the time I have no trouble with identifying what she wears. Iīve tested a few other womenīs frags and I donīt think that those were very similar either. But many are sweet and have floral or fruity elements, thatīs true.
The interesting thing is, my GF often says that all the male fragrances are VERY similar to her. Itīs all woods, musk and spices, she says! Blasphemy, I know. Sheīs unable to recognize even the most distinctive ones I have (IMO). For her itīs just good/bad/I donīt care, lol. Maybe itīs just easier to see the differences, if you are more familiar with those fragrances (I donīt know the ones youīve mentioned)? I donīt know, let the pros decide on this one.
