It would be futile of me to try and describe this when others have done a far better job already. Read the wonderful review by @Varanis Ridari who delves into some of the history if you're interested. For those who don't like reading long reviews @Colbourne sums it up perfectly with '...sort of a citrus cologne with a dash of fougere in the drydown'.
There's something quite lovely about simplicity. Perfect for a warm spring day.
SOTD : Hermes Eau d'Hermes. Current version. Lacks the spices (esp cumin) of batches from only a year past. On my skin is citrus, clean pale leather, a hint of musk, and an even fainter hint of spice. Oh dear, this is so polite and nice. OTOH, into the work rotation it goes, so it will be worn.
