As a novice with scents, I am cautious to offer opinions. Many of the components are new to me.
I've never tried RoseOtto before, the opening seemed a bit like patchouli, then showing a keenness of rose; settling into a subtle vetiver and sandalwood partnership overcast by some scents of unknown essence. Very precise. For Holmes not Watson.
Nothing special about 88 to me. Smells like an expensive soap. Smells more feminine to than unisex. Not a bad fragrance, just not for me.
Two components are dominant on my skin: a dark, harsh and earthy Vetiver root, and a deep, rich, dark Rose Otto. Darkness concentrated. Geranium provides for glimpses of light, akin to sun rays breaking through the small windows in an old Gothic church. Impressions of incense and of a medicinal licorice are added in the drydown, and the base develops sandal wood that has a waxy undertone. Darkness, Victorian, Edwardian formal assertiveness in a bottle. At times with edges, harshness, and composed of excellent raw material.
Porformance is excellent, with great projection, strong sillage and about nine hours of longevity on my skin. A classic dark woody/floral creation. 4/5
A dark, humid, camphoraceous masculine chypre centered on rose, sandalwood, bergamot, with earthy-mossy notes and an overall kind of dusty-musky breeze. Dense and slightly animalic at first, shady and strong, not far from classic stuff ŕ la Cabochard, just less complex, more woody and masculine, and without leather, but that is the mood – a nostalgic, a bit "heavy" and to be honest, boring after a while, austere and elegant fragrance, quite in a decadent meaning. The drydown features mostly a sort of dark-soapy note with nuances of wet dead roses. Not bad, not stunning, frankly a bit plain and monotone (above all because of a general humid "heaviness), but if you like the – few – notes, then it may work for you.
Pluran mentions No. 88 in his review of Montale's Black Aoud, and the comparison is quite apt. Both are rich, dark, woody rose scents of tremendous intesity. I agree with pluran's assertion that No. 88 is the more complex and rounded of the two. It's more polished than Black Aoud, but that extra polish makes it less arresting than the Montale scent. Both are outstanding masculine rose-based fragrances, but I prefer the blunt savagery of Black Aoud to the sophisticated romance of No. 88. Personal preferences aside, No. 88 is a great scent, and a "must-try" for anybody who assumes that roses are not meant for men.
