Shaal Nuur without a doubt. This may seem a bit biased as I HATE Idylle
First coming from a Guerlain lover, not having a smidgen of Guerlinade or even a 'Guerlain'-like feel to it was utterly disappointing. I was hesitant even to try it after reading all the negative reviews. When I first did, I was overwhelmed by a HUGE pear note that smelled chemical and ruined the entire fragrance. Idylle dries down (not very long after you spray I might add), very, very, very similarily to NR for Her EDT and SJP Lovely. Now I'm a huge fan of NR for Her, but the topnotes of Idylle are extremely synthetic and cloying (to me). I don't understand how some people don't get the NR or Lovely connection. If you smelled Idylle's sillage you get easily mistake it for NR or Lovely! It would work well on a man though, I just have to say. I even smelled Idylle on a friend of mine and mistook it for NR. I know, I know...I'm beginning to sound like a broken record
As a Guerlain-lover yourself N_Tesla, you owe yourself to atleast try Shaal Nur. When I first tried it over a year ago, I was struck at how similiar it was to something...something...yet I didn't know what it was. I was pretty sure I had it. I immediatly got the Guerlain connection. I compared it to Shalimar, but that seemed wrong. So as soon as I got home, I read Turin's review and... BAM! Vol de Nuit was the fragrance Shaal Nur was evoking. It evokes that same mysterious feeling and has that lovely Guerlinade oozing from top to bottom. Think of it as a cross between the deep animalicity of the vintage VdN parfum and the breadlike, bright iris from the current EDT. It truly is a masterpiece.
