I smell of virtually odorless Ivory soap, natural lanolin, jojoba & castor oil and a small amount of fragrant Oleg Cassini's 'Cassini', used only on my wrist immediately following a shower. Occasionally I switch to 'Juicy Couture' or Jo Malone 'Pomegranite Noir' but recently have tried & liked the 'Cassini'.
In my long history of enjoying good fragrances, I've known & loved some wonderful perfumes which, unfortunately, are no longer fully available in the U.S., including Nina Ricci's 'Fille d'Eve', Gerlain's 'Mitsouko', & Jean Despres' 'Bal á Versailles', any one of which I'd still use otherwise. I've also loved Chanel 'No 5' but it seems to have been altered in formula or else is now different on me. One's chemistry does change.
I've been able to detect a presence of out-of-view older women while shopping by an identifiable stale perfume aroma. Perhaps their bottles have become stale, perhaps it's a matter of body chemistry or meds they take (I take none). It's vital to me to avoid that, whatever it requires, even if it meant avoiding perfume completely. Respect for others is why I keep my current supplies fresh & apply only one little spray on my wrist & that, only following a shower. Then it's refreshed only following my next shower. It is keeping it smelling fresh, which is the only acceptable effect as far as I'm concerned.
It's also advisable to avoid wearing perfume when going to see the dentist or for any other close-proximity professional exam. It must be stifling for them at times! No wonder they wear those face masks :-)
