Sniffing swiftly through the relatively new offerings at a Guerlain counter, this riveted attention and I came away with a sample. I wouldn't have guessed it is a fairly new Guerlain because, unlike with L'Instant and L'Instant Magic, I can actually breathe while smelling this scent. Mind you, it does tickle my nose with something, perhaps the pink pepper, but not to the point I'm actually gasping. Rather, the beautiful heart of Almond, Rose and Orange blossom captivates throughout, Vanilla adding sweetness from the base. Were it not for the pink pepper this would go straight on my wish list, but I need to live with it awhile to see if I keep breathing the whole time it's on. Not surprised that Thierry Wasser designed it, rather than those responsible for previously mentioned ones. The name translates to "The Most Beautiful Day of My Life," i.e., a wedding or engagement or birth of a child. The fragrance may not be terribly unique or quite in the same league with Guerlain's fully breathable entrancing greats (Vol de Nuit, Jardin de Bagatelle, etc, etc,) but this is still a lovely perfume, not an olfactory mistake.
p.s. Finally had to wash it off. The breathability didn't improve. Those not sensitive to chemicals may enjoy.
