I am this close to buying a bottle of Kelly Caleche, for a few reasons: 1) My disappointment in Tom Ford for Men, I need some kind of consolation. No? It sounds good to me! 2) It is a scent that a man could wear - the first time my BF and I smelled this in the Hermes boutique, and I told him it was a scent for women, he thought I was joking him. He said he couldn't imagine a woman liking it, it seemed like a mens fragrance to him. 3) The rose and bright floral combo does exactly what you described: disappears, reappears, disappears, reappears - in classic Jean Claude Ellena style. Even if you don't like what the Hermes' scents smell like, you gotta admire what this man does with molecules!
However, here's the reasons why I haven't bought it: 1) I get absolutely NO leather from KC on my skin...WTF? 2) The rose note in KC is extremely similar to the rose note in Rose Ikebana by Hermes (Hermessence) and I already own Rose Ikebana. Rose Ikebana however is more about rhubard and it's really soft, where KC is much more stronger and well...less fruity. Do I need two Hermes scents with similar rose notes?? 3) Partly due to my previous comment, will I wear KC enough, to warrant a full bottle?
IMO - if you don't own Rose Ikebana, go for it. It is not a JC Ellena/Hermes 'classic' (like Terre d"Hermes) but it fills that 'modern rose' niche that Hermes' competition (L'Artisan, Le Labo, Montale, C&S, etc.) has had for years now. 'Modern rose' scents that men have been wearing for some time now.
