There was plenty to like about Narciso by Narciso Rodriguez, which launched as an Eau de Parfum in 2014. The white cube bottle was perfect, and perfumer Aurélien Guichard's composition, which I likened to "a very thin schmear of gardenia marshmallow fluff on a wood plank", struck a nice balance between wearable and fun. I'm no longer in buying mode, but I would not at all mind having a small bottle.
The new Eau de Toilette is clearly related to the Eau de Parfum, but as you'd expect, it inches farther along the line towards wearable. The opening is still "raspy, citrus + dry herbs + plant stems + fruit" but it's more transparent now, and the dry down replaces the gardenia of the Eau de Parfum with what they call a "delicate combination of peony and Bulgarian rose" and what I would call "generic pink perfume flowers". The base is likewise lighter and paler: less powder and vanilla, less wood and vetiver, a cleaner rendition of musk.
Verdict: Narciso Eau de Toilette smells younger and fresher than the Eau de Parfum. It probably works better for warm-weather wear, and will be undoubtedly easier to wear to the office. I did not find it objectionable to wear, but nor did I find it fun, or interesting, or memorable. Wearing the two versions together mostly served to remind me how good the Eau de Parfum is. The reviews I've seen so far have been overwhelmingly positive, though, so the Eau de Toilette is certainly worth a try, especially for anyone who found the Eau de Parfum too much.
Narciso by Narciso Rodriguez Eau de Toilette is available in 30, 50 and 90 ml.
