Both fragrances are undebatably jasmine-focused, but they're very different. A La Nuit is a deep pool of silk and honey; Jasmin 17 is powder and lace. Jasmin 17 is brighter and fresher and more frilly-flowery than A La Nuit, and in my days of lower jasmine tolerance, I preferred that.
But now I think I prefer drowning to frills. This scent is lovely for a few minutes, but I grow tired of it. Too much lace, too much powder, and I think too much neroli - I've never liked neroli for more than a few minutes.
Which leads me to the notes - according to Legerdenez, they're Jasmine, litsea cubeba, neroli, palma rose, bigarade, amber, musk, sandalwood, and vanilla. A lovely sounding collection, and I once enjoyed the result very much, but now it's been bumped out of my list of favorites. For a full-strength dose of jasmine, I prefer A La Nuit; for a casual jeans-and-sneakers summery-day jasmine, I'll take Jo Malone White Jasmine & Mint.
